How to solve trig equations with sin and cos
Web2. I was doing some math work, and have to solve two trig equations simultaneously, but have no idea how to approach this, can anyone help, just need to be pointed in the right direction. I have to solve for T 1 and T 2 using these equations: T 1 sin ( 45.0) + T 2 sin ( 30.0) = 0.00. T 1 cos ( 45.0) + T 2 cos ( 30.0) = 1720.
