Hi Michel,
What I mean is that in your example formula (not in the general form formula, that one is correct), theta is missing completely. You wrote y=2sin[2(pi+pi/4)]+3 where you should have written: y=2sin[2(theta+pi/4)]+3.

Hi Michel,
Thanks for your lectures! I think you've made a little mistake in your formula's in this video that might make it a little confusing for some to comprehend what's going on. Instead of first pi, you should have written theta. Keep up the good work
