Question

please solve this problem

Answer 1

Solution is in the attachment.....

Answer 2

$\frac{cosA-sinA+1}{cosA+sinA+1}$

$\frac{cosA-sinA+1}{cosA+sinA-1} * \frac{cosA+sinA+1}{cosA+sinA+1}$

$\frac{cos^2A-sin^2A + 2cosA+1}{sin^2A+cos^2A+2sinAcosA-1}$

$\frac{cos^2A-sin^2A+2cosA+1}{1 - 1 + 2sinAcosA}$

$\frac{cos^2A - sin^2A+2cosA+sin^2A+cos^2A}{2sinAcosA}$

$\frac{2cos^2A+2cosA}{2sinAcosA}$

$\frac{cos^2A+cosA}{sinAcosA}$

$\frac{cos^2A}{sinAcosA} + \frac{cosA}{sinAcosA}$

$\frac{cosA}{sinA} + \frac{1}{sinA}$

cotA + cosecA.


Hope this helps!
