Linear Equations
One Variable  ax+b=0  a≠0 and a&b are real numbers 
Two variable  ax+by+c = 0  a≠0 & b≠0 and a,b & c are real numbers 
Three Variable  ax+by+cz+d=0  a≠0 , b≠0, c≠0 and a,b,c,d are real numbers 
Pair of Linear Equations in two variables
a_{1}x+b_{1}y+c_{1}=0 a_{2}x+b_{2}y+c_{2}=0 
Where
 a_{1}, b_{1}, c_{1}, a_{2}, b_{2}, and c_{2} are all real numbers and
 a_{1}^{2}+b_{1}^{2} ≠ 0 & a_{2}^{2 }+ b_{2}^{2} ≠ 0
It should be noted that linear equations in two variables can also be represented in graphical form.
Quadratic Equation and Formula
The standard form of a Quadratic Equation is:
ax^{2}+bx+c=0 where a ≠ 0
and \(\begin{array}{l}x = \frac{b\pm \sqrt{b^{2}4ac}}{2a}\end{array} \)

Algebraic formulas
 (a+b)^{2 }= a^{2 }+ b^{2 }+ 2ab
 (ab)^{2 }= a^{2 }+ b^{2 }– 2ab
 (a+b) (ab) = a^{2 }– b^{2}
 (x + a)(x + b) = x^{2} + (a + b)x + ab
 (x + a)(x – b) = x^{2} + (a – b)x – ab
 (x – a)(x + b) = x^{2} + (b – a)x – ab
 (x – a)(x – b) = x^{2} – (a + b)x + ab
 (a + b)^{3} = a^{3} + b^{3} + 3ab(a + b)
 (a – b)^{3} = a^{3} – b^{3} – 3ab(a – b)
 (x + y + z)^{2} = x^{2} + y^{2} + z^{2} + 2xy + 2yz + 2xz
 (x + y – z)^{2} = x^{2} + y^{2} + z^{2} + 2xy – 2yz – 2xz
 (x – y + z)^{2} = x^{2} + y^{2} + z^{2} – 2xy – 2yz + 2xz
 (x – y – z)^{2} = x^{2} + y^{2} + z^{2} – 2xy + 2yz – 2xz
 x^{3} + y^{3} + z^{3} – 3xyz = (x + y + z)(x^{2} + y^{2} + z^{2} – xy – yz xz)
 x^{2 }+ y^{2} =½ [(x + y)^{2} + (x – y)^{2}]
 (x + a) (x + b) (x + c) = x^{3} + (a + b +c)x^{2} + (ab + bc + ca)x + abc
 x^{3} + y^{3}= (x + y) (x^{2} – xy + y^{2})
 x^{3} – y^{3} = (x – y) (x^{2} + xy + y^{2})
 x^{2} + y^{2} + z^{2} xy – yz – zx = ½ [(xy)^{2} + (yz)^{2} + (zx)^{2}]

Arithmetic Progression(AP) Formulas
If a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, a_{6},_{…} are the terms of AP and d is the common difference between each term, then we can write the sequence as; a_{, }a+d, a+2d, a+3d, a+4d, a+5d,….,nth term… where a is the first term. Now, n^{th} term for arithmetic progression is given as;
n^{th} term = a + (n1) d 
Sum of the first n terms in Arithmetic Progression;
\(\begin{array}{l}S_{n}=\frac{n}{2}[2a+(n1)d]\end{array} \) 
Trigonometry Formulas For Class 10
Trigonometry maths formulas for Class 10 cover three major functions Sine, Cosine and Tangent for a rightangle triangle. Also, in trigonometry, the functions sec, cosec and cot formulas can be derived with the help of sin, cos and tan formulas.
Let a rightangled triangle ABC is rightangled at point B and have ∠θ.
Trigonometry Table:
Angle  0°  30°  45°  60°  90° 
Sinθ  0  1/2  1/√2  √3/2  1 
Cosθ  1  √3/2  1/√2  ½  0 
Tanθ  0  1/√3  1  √3  Undefined 
Cotθ  Undefined  √3  1  1/√3  0 
Secθ  1  2/√3  √2  2  Undefined 
Cosecθ  Undefined  2  √2  2/√3  1 
Other Trigonometric formulas:
 sin(90° – θ) = cos θ
 cos(90° – θ) = sin θ
 tan(90° – θ) = cot θ
 cot(90° – θ) = tan θ
 sec(90° – θ) = cosecθ
 cosec(90° – θ) = secθ
 sin^{2}θ + cos^{2} θ = 1
 sec^{2 }θ = 1 + tan^{2}θ for 0° ≤ θ < 90°
 Cosec^{2 }θ = 1 + cot^{2} θ for 0° ≤ θ ≤ 90°

Circles Formulas For Class 10
 Circumference of the circle = 2 π r
 Area of the circle = π r^{2}
 Area of the sector of angle θ = (θ/360) × π r^{2}
 Length of an arc of a sector of angle θ = (θ/360) × 2 π r
(r = radius of the circle)
Surface Area and Volumes Formulas For Class 10
The common formulas from the surface area and volumes chapter in 10^{th} class include the following:
 Sphere Formulas

Surface area of sphere  4 π r^{2} 
Volume of Sphere  4/3 π r^{3} 
 Cylinder Formulas
Curved surface area of Cylinder  2 πrh 
Area of two circular bases  2 πr^{2} 
Total surface area of Cylinder  Curved surface area of Cylinder + Area of Circular bases = 2 πrh + 2 πr^{2}

Total surface area of cuboid  2(l×b + b×h + l×h) 
Volume of Cuboid  l × b × h 
Here, l = length, b = breadth and h = height. In case of Cube, put l = b = h = a, as cube all its sides of equal length, to find the surface area and volumes.
Statistics Formulas for Class 10
In class 10, the chapter statistics mostly deals with finding the mean, median and mode of grouped data.
(I) The mean of the grouped data can be found by 3 methods.
Direct Method:
where ∑f_{i }x_{i } is the sum of observations from value i = 1 to n
And ∑f_{i }is the number of observations from value i = 1 to n
Assumed mean method :
where a is assumed mean and d_{i} is deviation of a from each of the x_{i}.
Also, d_{i} = x_{i} – a
Step deviation method :
where
(II) The mode of grouped data:
l=lower limit of modal class.
h= size of the class interval
f_{1}= frequency of modal class.
f_{0}= frequency of the class preceding the modal class.
f_{2}= frequency of the class succeeding the modal class.
(III) The median for a grouped data:
l=lower limit of median class.
n= number of observations.
cf= cumulative frequency of class preceding the median class.
f= frequency of median class
h= class size

REALLY HELPFUL THANKS FOR THESE FORMULAS
where is arithmetic progressions? thats like the one most confusing topic for me atleast
Hi,
Learn all about Arithmetic progressions here in detail.
Arithmetic Progression (AP) is a sequence of numbers in order in which the difference of any two consecutive numbers is a constant value. Learn more here: Arithmetic Progression.
