Sin Tan formula

The law of sin or Tangent which is also called as sin-tangent formula or sin-tangent rule is the ratio of the sine of the angle to the cos of the angle in tangent formula

Tan Theta = Opposite / Adjacent

sin Theta = Perpendicular / Hypotenuse

Sin – Tan x formula

The Tan Theta is the ratio of the Opposite side to the Adjacent, where (Θ) is one of the acute angles.

Tan Theta = Opposite / Adjacent

sin Theta = Perpendicular / Hypotenuse

Tan alpha Questions

Out of other 6 trigonometry formulas, let’s have a look at the practice question of tan theta formula.

Question 1: If Sec x = 4/7, find tan x and sin x?

Solution: As Sec x = 1/cos x

4/7 = 1/ cos x

Cos x = 4/7

Tan2 x = sec2x – 1

= (4/7)2 – 1

= 16/49 – 1

= – 25/49

= – 5/7
