I know you wanted to cancel the sine, but really?

Visit https://brilliant.org/blackpenredpen/ to learn more trig! We can solve sin(2x)=sin(x) by using the double angle identity for sine but how do we solve the trig equation sin(πx)=sin(x)? Here I will show you a way to "cancel out the sine" when we have sine on both sides of an equation. Lastly, make sure you try cos(πθ)=cos(θ) 0:00 A challenge for all precalc and trig students 0:35 Q1 sin(2θ)=sin(θ) 4:12 Q2 sin(πθ)=sin(θ) 11:07 Check out Brilliant to learn more! 12:04 Question for you! cos(πθ)=cos(θ) Subscribe for more math for fun videos 👉 ‪@blackpenredpen‬ Subscribe for calculus & precalculus tutorials 👉 ‪@bprpcalculusbasics‬ 💪 Support this channel,   / blackpenredpen   🛍 Shop math t-shirt & hoodies: http://bit.ly/bprpmerch.
