The hypotenuse (H) is the longest side of the triangle opposite to the 90 degree angle. The other two sides are known as the base (B) and perpendicular (P) side. The formula to find the hypotenuse is the square of the hypotenuse equals the sum of the squares of the base and the ...
Most importantly here, First Quadrant Trig includes the elegantly-illustrated Angle-Sum and Angle-Difference Formulas (taken from one of my previous answers): Of course, the figures only seem make to make sense for αα, ββ, α+βα+β, and α−βα−β (strictly) between 0∘0...

How do I find the area, circumference, and perimeter of a circle? Find the derivative of f(x) = 2\cos(3x+2) Angles A and B are supplementary. The bigger angle is 30 degrees less than twice the degree measure of the smaller angle. Find the degree measure of the difference of ...
Rewrite the equation using trigonometic identities, such as the half-angle and double-angle identities, the Pythagorean identity and the sum and difference formulas so that there's only one instance of the variable in the equation. This is the most difficult step in solving trig functions, becau...
Establishing identities using the double-angle formulas is performed using the same steps we used to derive the sum and difference formulas. Choose the more complicated side of the equation and rewrite it until it matches the other side. Using the Double-Angle Formulas to Verify an Identity Verif...
(E) Derivative of f(x) = tan-1(x) on (-½,½) If y = tan(x), then to make the inverse, x = tan(y) and we can use implicit differentiation to find dy/dx But can we make a substitution for sec2(y)??
