Thanks for all of your replies. This question is getting a little over my head to solve it algebraically. I graphed each functions (sin5t) and (4cos6t) and found the intersecting point, which works out to the 0's. This worked out to 0.224, 0.76, 1.3, 1.842 seconds (during the first 2 second...

Yes, I just double checked. The original equation is d=4(sin5t-4cos6t)

Yeah it got out of control pretty quick, using the angle sum/difference identities. I can graph it through Desmos and find the zeros that way...but it doesn't help with my assignment. Teacher is looking an algebraic solution, with an equation to represent the zeros.

Yes, I am familiar with that. Duh, I never thought to try...I'll give it a go, thanks!

Homework Statement 1. A weight hangs from a spring. If a force is applied to the weight at t = 0 seconds, it will start moving up and down. The following equation gives the distance d, in centimetres, of the weight from its equilibrium point: d=4(sin5t-4cos6t) At what times during the...
