(a) Find the indeﬁnite integrals of the following functions
(i) f(t)=27 cos(9t)+4e^(-12t)
(ii) g(x)=(14+45x^3)/x (x >0)
(iii) h(u)=(sin)^2 (1/4u)
(c) (i) Write down a deﬁnite integral that will give the value of the area under the curve
y=x^3cos(2/5 x) between x=1/2pi and x = pi
(The expression x^3cos(2/5 x) takes no negative values for 1/2pi ≤ x ≤ pi
You are not asked to evaluate the integral by hand.)
