(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
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?....
x Angle in radians.Return ValueThe cosine or hyperbolic cosine of x. If x is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result of a call to cos, cosf, or cosl occurs.By default, if the result is too large in a cosh, coshf, ...
You can find approximate cosine values without acalculatorby using the cosine ratio. Cosine A is equal to the length of the leg adjacent to angle A divided by the length of the hypotenuse. How do you convert cosine to an angle? To convert a cosine value to an angle, you need to find...
