Find the points on the given curve where the tangent line is horizontal or vertical. (Assume 0 ≤ < . Enter your answers as a comma-separated list of ordered pairs.) r = 6 cos()

answer: was that a question or answer?

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

what's the question here?
