Find the angle with which the graph of the function h (x) = sinbx intersects the x axis

 

[Harry_the_cat]

Ok so where does the function cut the x-axis?

Find the angle with which the graph of the function h (x) = sinbx intersects the x axis

Do you know how to find a derivative? Or, since you put this under trig, do you need to use a different method?

Do you know how the derivative (slope or gradient) is related to the angle?
