Some examples of using reciprocal, quotient, and Pythagorean identities to prove trigonometric identities.
Some examples of using reciprocal, quotient, and Pythagorean identities to prove trigonometric identities.
find the common denominator which will be cos . treat it like a fraction . so 1+sin over the common denominator which is cos. since cos into cos times 1 = 1 . and cos into cos times sin = sin. therefore your answer will be 1+sin/cos
separate them out like 1/cosx +sinx/cosx
