How to really solve sin(x^2)=sin(x)

We will go over a challenging trigonometry equation sin(x^2)=sin(x). This question usually causes many students to make the common mistakes of "canceling out the sin( )" and then "dividing both sides by x". So how do we really solve this equation? The key is to know the period of sine and the identity that sin(x)=sin(pi-x).This is a great exercise for trigonometry and precalculus students. 0:00 The wrong way of solving sin(x^2)=sin(x) ----------------------------- I help students master the basics of math.
