Use the trapezium rule with 3 strips to estimate the value of
∫0π2cos(x2) dx \int_0^{\pi} 2 \cos\left(\frac{x}{2}\right) \, dx ∫0π2cos(2x)dxFind the exact solution to
∫0π2cos(x2) dx \int_0^{\pi} 2 \cos\left(\frac{x}{2}\right) \, dx ∫0π2cos(2x)dxHence find the percentage error in the answer to part a
