(4)m=cos x(0)- sin x(1)(5)m=-sin x(6)For x=0, the rate of change is 0.For x=π2, the rate of change is -1. For x=π, the rate of change is 0. For x=(3π)2, the rate of change is 1.反馈 收藏
To this solution. Thus, the solutions arex=π4+kπwhere k is any integer. The graphs intersect for these values of x. You should use your calculator to check that, correct to three decimals, these are the same values as we obtained in Solution 1. ...
It is interesting to note that the value of cos changes according to the quadrants. In the above table, it can be seen that cos 120°, 150° and 180° have negative values while cos 0°, 30°, etc. have positive values. For cos, the value will be positive in the first and the ...

Our cos-1 calculator is very easy to operate! You enter the argument x, and the value of cos-1(x) appears in the blink of an eye. But please remember that you must not enter values that are not between -1 and 1! Have you noticed our tool *converts between radians and degrees?....
