WebMar 25, 2015 · 1 Answer Jim H Mar 25, 2015 The quadratic formula can be useful in solving trigonometric (or other) kinds of equation. But strictly speaking, the quadratic formula is used only to solve quadratic equations. Here is an example: We can use the quadratic formula to solve 2x2 − 6x +3 = 0. We get x = −( −6) ± √( −6)2 − 4(2)(3) 2(2) = 3 ± √3 2 WebMar 26, 2016 · Put the expression on the left side of the equation in the y menu (the graphing menu) of your calculator. Put the expression on the right as a second entry. (Be sure your calculator is set in the radian mode.) y1 = cos 2 x. y2 = 2cos x. Set the window of your calculator to show the graphs. Set the x values from –2 π to 2 π.
