How can we help?

I love Khan Academy and the exercises and videos have really helped me when I was struggling! I was going through the Trigonometry course to supplement another course that I was taking, but the Trigonometry course was lacking in a few things:

cofunction identities
half angle identities
power reducing formulas
product to sum / sum to product

Adding these would be beneficial to the course. Thanks for considering it!

Hi Daniela - I have been waiting for the Trigonometry section to be completed for over two years. Sadly, it looks like almost nothing has been added to it since 2015. Leaving meaningful STEM course like Trigonometry basically half finished for four years boggles my mind. Was this an oversight or does someone at Khan Academy hate trig?
