you solve secant angles when you have the hypotenuse and adjacent sides. sec=1/cos or, cos^-1 (reciprocal identity property)Tangent is solved when you have adjacent and opposite sides, or you can...
If you have a function f(x), then the tangent can be found by deriving f, denotedd/dx(f(x)) = f'(x). This will give the slope of f(x) at a certain point (a,b). find f'(a), call this m. Now, use the...
