pls prove it... class 10

Answer 1

:

Step-by-step explanation:

$\\\frac{1+tanA }{2sinA } +\frac{1+cotA}{2cosA } \\\\\frac{1+tanA }{2sinA} +\frac{1+\frac{1}{tanA} }{2cosA}\\\\\frac{1+tanA }{2sinA }+\frac{1+tanA}{2cosA*tanA}\\\\\\\frac{1+tanA }{2sinA }+\frac{1+tanA }{2sinA} (as,tanA*cosA=\frac{sinA}{cosA}*cosA=sinA)\\\\\\\frac{2(1+tanA) }{2sinA }\\\\\frac{1+tanA}{sinA} \\\\\\\frac{1}{sinA} +\frac{tanA}{sinA} \\\\cosecA+secA\\RHS=LHS$
