Regula - falsi method

Solve the following for a positive root by False position method

1.    xe^x = 3

2.    4x = e^x

3.    x log x = 1.2

4.    tanx + tanh x = 0

5.    e^-x = sin x

6.    x³-5x-7=0

7.    x³+2x²+10x-20=0

8.    2x-log x = 7

9.    xe^x = cos x

10.           x³-5x+1=0

11.           e^x = 3x

12.           x²- log x =12

13.           3x – cos x =1

14.           2x – 3sin x =5

15.           2x = cos x +3
