$\sin\left(a\right)=a\sqrt{\sin\left(a\right)^2}$
Learn how to solve equations trigonométriques problems step by step online. Solve the equation sin(a)=(1-cos(a)^2)^(1/2)a. Applying the trigonometric identity: 1-\cos\left(\theta \right)^2 = \sin\left(\theta \right)^2. Apply the formula: \left(x^a\right)^b=x, where a=2, b=1, x^a^b=\sqrt{\sin\left(a\right)^2}, x=\sin\left(a\right) and x^a=\sin\left(a\right)^2. Apply the formula: a=b\to a-b=0, where a=\sin\left(a\right) and b=a\sin\left(a\right). Factor the polynomial \sin\left(a\right)-a\sin\left(a\right) by it's greatest common factor (GCF): \sin\left(a\right).
