How do i solve trig equations on this? And also factoring.
It seems the calc doesnt recignie cos^2_x keeps saying missing (
I want to factor and solve for x by putting in cot x cos^2x-2cot x
How do i put it in?
Thanks!
you should be familiar with the vertex form of a parabola ...
$\displaystyle y = a(x-h)^2 + k$
sub in the given vertex coordinates $\displaystyle (h,k)$ and the coordinates of the given point $\displaystyle (x,y)$ ... solve for $\displaystyle a$ , then graph.
btw ... next time state what you are graphing. if you had not mentioned a vertex, I would've had no idea what you wanted graphed in the first place.
