Question

can u please solve this sum

Answer 1

Given (cosecA-sinA)(secA-cosA)(tanA+cotA).

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

$(\frac{1-sin^2A}{sinA} )( \frac{1-cos^2A}{cosA} )( \frac{sin^2A + cos^2A}{cossinA} )$

$\frac{cos^2A}{sinA} * \frac{sin^2A}{cosA} * \frac{1}{cosAsinA}$

1.


LHS = RHS.


Hope this helps!
