Question

If sine of an angle is ¼ and cosine of an angle is 15/4.. find cosecant.

Answer 1

cosec of an angle is 4.

Answer 2

csc = 1/sin = 4 indeed

Answer 3

The cosine of an angle cannot be 15/4. It must lie within a range of -1 to 1.

The cosine of an angle with sin of 1/4 is sqrt(1 - sin^2x) = (sqrt15)/4. You probably left out the square root sign.

I agree with the others about the cosecant
