Question

The root of $x+tanx=0in[1,2]$ using secant method by performing one iteration is______(Answer upto two decimal places).

• A. 1.93

Answer 1

The correct option is A 1.93
Now, $x_1=\frac{af\left(b\right)-bf\left(a\right)}{f\left(b\right)-f\left(a\right)}=\frac{1\ast [2+tan2]-2[1+tan1]}{(2+tan2)-(1+tan1)}$

= 1.93
