# GDC comparisons

In order to compare the equation solvers on these models, let"s consider the following Maths SL exam question. Let"s look at only part (c). The answers to the previous parts are: (a) r=− 4 , (b) p=8, q=π12 .Therefore, to answer part (c) we need to solve for x in the equation 8cos(π12(x−4))+10=7 in the interval 0≤x≤20 .The entire question is worth 8 marks, and part (c) is worth only 2 marks. For...
