Obvioulsy we e after an identity connecting tangent and secant. How about this one?
You may ask, but in my equation I have This is easily solved by saying So, hopefully you can rearrange the identity to get Putting this into our equation gives Now let’s get rid of that horrible tangent by saying This leaves us with the equation We will now square both side, but remember that when we square the equation , we will also have the solutions to so you must check any solutions you get work in your original equation. Anyway, squaring gives This rearanges nicely to But we have solved for p, and we need to solve for x.
