Thank you sm this is helping so much in precalc
really great videos, you've been a major help in my trig, do you have any videos on the sum and difference formulas for trigonometry identity's? I could not find one and did not know if i missed it. Again these videos have been really helpful

Thank you so much, this really helped me a ton on my pre calc test! I love the way that you explain things, and your videos are always super clear! Do you have any videos about pythagorean identities?
