$\int_{-3}^{0}\left(t+3\right)\cos\left(\frac{\pi}{3}nt\right)dt$
Learn how to solve problems step by step online. Integrate the function (t+3)cos((npi)/3t) from -3 to 0. Take \frac{\pi }{3} out of the fraction. We can solve the integral \int\left(t+3\right)\cos\left(\frac{\pi}{3}nt\right)dt by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du. Now, identify dv and calculate v.
