### TRIGONOMETRY

Trigonometry’s the first step into some of the math big-leagues, and it’s not hard to see why. Finding side lengths from angles and angles from sides? Explore this section to learn more about SOHCAHTOA, sines, cosines, and tangents, all major parts of learning trig. Who knew that triangles were so tricky? Lucky for you, whether you need to find right triangles’ angles or the hypotenuse, we’ve got your back!
