Question

prove that
sin2
y x cot y x cosec y = cos y
with process and solution please​

Answer 1

Question

sin^2y x cot y x cosec y = cos y.

Solution

L.H.S.

=> sin^2y x cot y x cosec y .

=> sin^2y ×cos y/sin y × 1/sin y.

sin y will be cancelled out.

=> cos y.

=> R.H.S.

Formula used.

• cot y= cos y/sin y.
