To prove thatcosθ1+sinθ=tan(π4−θ2), we will start with the left-hand side and manipulate it step by step. Step 1: Rewritecosθandsinθusing half-angle identities We know that: cosθ=cos(2⋅θ2)=cos2(θ2)−sin2(θ2) ...
Step 3: Use half-angle identitiesUsing the half-angle identity, we have:1−cos(θ)=2sin2(θ2)andsin(θ)=2sin(θ2)cos(θ2)Thus, we can express f(x) as:f(x)=tan−1⎛⎜⎜⎝2sin2(θ2)2sin(θ2)cos(θ2)⎞⎟⎟⎠=tan−1(tan(θ2))This simplifies to:f(x)...
