Step 2: Expressing cot7θFrom the rearranged equation, we can express cot7θ:cot7θ=1−cotθcot4θcotθ+cot4θ Step 3: Using the Cotangent Addition FormulaRecall the cotangent addition formula:cot(a+b)=cotacotb−1cota+cotbIn our case, let a=θ and b=4θ. Then:cot(5θ)=cotθ...
2 - 2 sin2x = 5 sin2x - sin x 0 = 7 sin2x - sin x - 2 This is a quadratic in sin x. You will need to use the quadratic formula to solve this, as it cannot be factored. This probably means that the solutions for x may not be writable in exact form. ...
