The quotient rule

Given the function f(x)=g(x)h(x)−excos⁡xf\left(x\right)=\dfrac{g\left(x\right)}{h\left(x\right)}-e^x\cos x, and given g(π2)=2g\left(\dfrac{\pi}{2}\right)=2, g′(π2)=3g'\left(\dfrac{\pi}{2}\right)=3, h(π2)=1h\left(\dfrac{\pi}{2}\right)=1, and h′(π2)=2h'\left(\dfrac{\pi}{2}\right)=2, find f′(π2)f'\left(\dfrac{\pi}{2}\right).
