cosx=√1−sin2xWe square both sides to eliminate the square root:cos2x=1−sin2x Step 2: Use the identity for sineRecall the identity for sine:sin2x=2sinxcosxSubstituting this into the equation gives:cos2x=1−2sinxcosx Step 3: Rearrange the equationRearranging the equation, we have:...
We can use the identity 1+cosx=2cos2(x2). Thus, we can rewrite the integrand: 11+cosx=12cos2(x2)=12sec2(x2). Step 2: Change the variableLet u=x2. Then, dx=2du. The limits change as follows:- When x=π4, u=π8.- When x=3π4, u=3π8. Now, the integral becomes:...
