Question

Express sin in terms of sec,cos,cosec,tan and cot​

Answer 1

Answer :

The easiest way to do this is to start with the Pythagorean identity,

solve for the sine in terms of cosine and replace each cosine with 1 over its reciprocal (which is secant):

The radical has a fraction in it. A better form is to simplify that fraction, so find a common denominator and split the fraction into two radicals — the bottom one of which you can further simplify:

The last function to write sine in terms of is the cosecant. The reciprocal of cosecant is sine, so this equation is just one of the basic reciprocal identities:
