1. Express cosx and sinx in terms of n and m: From the first equation, we can express cosx as: cosx=ncosy From the second equation, we can express sinx as: sinx=msiny 2. Use the Pythagorean identity: We know that: sin2x+cos2x=1 Substituting the expressions for sinx and cosx: (...
We can express sinx+cosx in terms of sinx and cosx:sinx+cosx=√2sin(x+π4)Now, substituting this back into the integral:I=1√2∫√2sin(x+π4)√sinxcosxdxThis simplifies to:I=∫sin(x+π4)√sinxcosxdx Step 4: Substitute t=sinx−cosxLet t=sinx−cosx. Then, differentiating ...
