WebbE.g. (x + 5)(x − 1) = x 2 + 5x − x − 5 = x 2 + 4x − 5. Remember: expressions with three terms like x 2 + 4x − 5 are known as trinomials. An expression that contains more than two terms and includes variables and coefficients is called a polynomial. Webb9 maj 2016 · Explanation: Let's draw a right triangle with an angle of a = cos−1(x). As we know cos(a) = x = x 1 we can label the adjacent leg as x and the hypotenuse as 1. The Pythagorean theorem then allows us to solve for the second leg as √1 −x2. With this, we can now find sin(cos−1(x)) as the quotient of the opposite leg and the hypotenuse. sin ... dvd on this device
