WebJun 30, 2015 · This question asks about the function: g(x) = ∫ 3 x cos(t) t dt. Clearly, in this question we have f (t) = cot(t) t. Notice that FTC 1 requires the constant to be the lower limit of integration, so we use the properties of definite integral to write: g(x) = − ∫ x 3 cos(t) t dt. Now, we can see that g'(x) = − cos(x) x. WebMar 23, 2024 · Explanation: In parametric form of equation f (t) = (x(t),y(t)) dy dx = dy dt dx dt. Here x(t) = tcos2t and y = t2sint − cost. and therefore dx dt = cos2t − t ×2cost × ( − sint) = cos2t +2tsintcost. and dy dt = t2cost +2tcost + sint.
