SUMMARY

The equation A sin(Bt) - Ct + D = 0 is a transcendental equation that requires numerical or graphical methods for solving. To approach this, first rearrange the equation to A sin(Bt) = Ct - D. By plotting both sides of the equation on the same graph, the intersection point will yield the value of t that satisfies the equation. This method effectively visualizes the solution and is essential for handling equations with both trigonometric and linear components.

Hello,

I have an equation which I am trying to solve for t. Of course the problem I'm having is due to the combination of ts within the argument of the sin term and also outside of it. I think I could also manage without the constant D (using sin(x)/x=sinc(x)), but that's no help here (as far as I can tell). Any advice is appreciated! Here's the equation:

[tex] A \sin \left( B t \right) - C t + D = 0[/tex]

Thanks,

Kerry

This is a transcendental equation which has to be solved numerically or graphically. First rewrite the equation with the sin term on the left and the linear term on the right:

A sin(Bt) = Ct - D

Now plot on the same graph, the function on the left and the function on the right. Their intersection gives the value of t which solves your original equation
