Answer:
hey here is your solution
pls mark it as brainliest
so here we go
Step-by-step explanation:
now consider lhs=sin/1-cos
and rhs as cosec+cot
now beginning from lhs
sin/1-cos
so conjugate of 1-cos is 1+cos
so now by applying conjugate method
we get
sin(1+cos)/1-cos square
so as 1-cos square=sin square
we get
sin(1+cos)÷sin square
ie 1+cos/sin
so 1/sin+cos/sin
so we know that 1/sin=cosec and cot=cos/sin
hence cosec A+cot A
hence lhs=rhs
thus proved
