WebbFor θ = π you have LHS: sin(2π)+cos(2π) = 0+ 1 = 1 RHS: sinπ +cosπ = 0+(−1) = −1 hence the equality does not hold and can't be proven. How do you find the value of sin20(θ) … Webb6 apr. 2024 · Explanation: If you do sin(x)2, that means you are squaring the angle, instead of the value of sin(x). For example: sin(30∘)2 = sin(900∘) = sin(180∘) = 0. is different …
