Look at step-by-step explanation.
Step-by-step explanation:
First write everything in terms of sin and cos:
(sinx)(sinx/cosx) + (sinx)/(sinx/cosx) = (1/cosx)
Then simplify the expression where you can:
(sin^2)/(cosx) + (cosx) = (1/cosx)
Next find a common denominator and add the two numbers on the left side of the equation:
(sin^2)/(cosx) + (cos^2x)/(cos^2x) = (1/cosx)
((sin2^x)+(cos2^x)/(cosx)) = (1/cos)
Finally, use the identity, sin2^x + cos2^x = 1, to simply to numerator:
(1/cosx) = (1/cosx)
