How would you sketch y = xsecx???????

 

[Templar]

Sketch y=x, y=Sec[x] on one graph and multiply them together.

Hehe, easier said than done, it's hard to determine where the curves intersect, so you'll need to multiply several ordinates together and see what the shape of the curve is from the points you plot.

how do you multiply coordinates?

 

[Mumma]

A(a_x,a_y) * B(b_x,b_y) = C(a_xb_x,a_yb_y) ? i guessed

 

[Riviet]

A(a_x,a_y) * B(b_x,b_y) = C(a_xb_x,a_yb_y) ? i guessed

Yep, you got the idea.
The important parts of the graph to look for are when the curves cross the lines y=+1 as well as x-intercepts of either curve as these points are easiest to plot.

One more thing use y=1 and y=-1 as a point that it always crosses
