$\frac{2\cos\left(\frac{1}{2}\right)\cos\left(\frac{1}{2}\right)\left(a+b\right)\left(a-b\right)}{-2\cdot 0.479426\sin\left(\frac{1}{2}\right)\left(a+b\right)\left(a-b\right)}$
Learn how to solve polynomial long division problems step by step online. Simplify the expression (2cos(1/2)(a+b)cos(1/2)(a-b))/(-2sin(1/2)(a+b)sin(1/2)(a-b)). The sine of \frac{1}{2} equals 0.479426. The sine of \frac{1}{2} equals 0.479426. Multiply -2 times 0.479426. Multiply -0.958852 times 0.479426.
