Question

Please help me with this​

Answer 1

step one mein identity lagayi hai maine

(a - b)^2 waali and (a + b)^2 waali considering 1+ sinx = a and cosx = b

denominator mein multiplication ki hi bss simply

srep 2 mein (1 + sinx)^2 ki bhi identity khol di

neeche jo cancel hue vo cancel kr diye

step 3 mein jitne pair sin sq x + cos sq x k hai un sabki jagah 1 rakh diya baaki as it is likh diya

step 4 mein 4 common aa jayega and (1 + sin x) multiple bach gya

denominator mein cos square x ko 1 - sin square x likh diya

bahar - tha to thoda direct kr diya = sin square x - 1 aa jayega

fir 1 cancel ho gya

step 4 k baad

denominator se 2sin x common aa jayega

and (1+ sin x ) upr neeche se cancel ho jayenge

finally 2/sinx = cosec x

oye follow kr dena itna bada solve kiya hai hath bhi dukhne lag gya
