Common Misconceptions > Cheatsheets > Problem solving tips > Important Diagrams > WebThe derivative turns out to be $-10\sin\left(2t+\frac{\pi}{4}\right)$. You wanted to find out where this is $0$, and used the formula for the sine of a sum. It is much easier to note that the derivative is $0$ when $2t+\frac{\pi}{4}$ is a multiple of $\pi$. But examining the derivative to find the maximum is not the best procedure here.

Weby = c1 cos(2t)+c2 sin(2t) To solve the non-homogeneous problem for a right hand side g(t) which is a sum of two different types of functions, we first separate it into two ODEs, one with right hand side g1(t) = t2 and the other with g2(t) = 3et. Considering the form of g1, we need to choose Y1 = At2 +Bt+C for the first ODE. WebFind the Derivative - d/dt sin(t)cos(t) Differentiate using the Product Rulewhich states that is where and .
