As the right triangle is circumscribed in a unit circle, the length of its hypotenuse equals the circle's radius (which equals one unit). Sine and cosine are the fundamental trigonometric functions arising from the previous diagram: The sine of theta (sin θ) is the hypotenuse's vertical pro...

Also, remember that tan q = sin q/cosq. So tan 110o will also be negative, since a positive number divided by a negative number will always give you a negative. As with most things on the unit circle, this whole train of thought takes more time to write out than it takes to actu...

See, Euler’s formula lets us draw a circle and read off a position. That’s amazing! We can avoid a lot of painful geometry with a few multiplications. If you’re doing any advanced math, letting Leonhard Euler deep into your soul is well worth it. He’s good company. That’s it...
The Unit Circle shows us thatsin2 x + cos2 x = 1The magic hexagon can help us remember that, too, by going clockwise around any of these three triangles:And we have:sin2(x) + cos2(x) = 1 1 + cot2(x) = csc2(x) tan2(x) + 1 = sec2(x)...

Sine and cosine live on the unit circle (radius 1). The other functions use a radius of secant (tan/sec) or cosecant (cot/csc).Q3: What's the swapped function?We make a mini-triangle by shrinking the original triangle down, and rotating so dx matches the side of length 1. It ...
