Product review & video
have you ever heard of the expression sohcahtoa what do you think this expression means in this lesson we're going to focus on right triangle trigonometry let's say if this is the angle theta now there's three sides of this triangle that it needs to be familiar with opposite to theta this is the opposite side and next to the angle theta is the adjacent side and across the box or the right angle of the triangle which is die upon this that's the longer side of the triangle now if you recall this is a B and C the Pythagorean theorem applies to right triangles a squared plus B squared is equal to C squared but we're not going to focus on that too much but just be familiar with that equation now let's talk about the six trig functions in terms of sine cosine tangent opposite adjacent hypotenuse sine theta according to sohcahtoa S is for sine o is for opposite H is for hypotenuse sine theta i
