How to draw the image of quadratic sine function How to draw the image of sin square and COS square p. S. is (SiNx) squared, not sin (xsquare)
(sinx)^2=1-(cosx)^2=cos2x/2+1/2
Will that happen
The same one

Mainly to take some special angle, such as 30 degrees and so on
On the problem of whether it is necessary to raise W when the image of sine function is shifted left or right F (x) = sin (2x - π / 4) for example, if we move the image to the left π / 8 units It is proposed that f (x) = sin2 (x - π / 8) be shifted to the left so that f (x) = sin2x is correct It is not correct that 2 F (x) = sin (2x - π / 8) By the way, I'd like to summarize when I need to put forward W and when not. Thank you very much
Translation is only for independent variables,
How to draw function image in WPS table? For example, sine function SiNx image
Menu insert → FX function Click to call up the "insert function" window. You can click and select it. You don't need to add single quotation marks at all, just add a comma "," after each parameter
On the calculation of area under the curve of sine function Please tell me. Draw an image of SiNx (x from 0 to pie/2) halo, PI can not be played out Make a vertical line of x-axis at point a (Pie / 2,1), and find the area of the figure under the function curve from the origin to point A. (approximate to ellipse)

The interval of sine function and cosine function being increasing function on [0,2 π]
The increasing intervals of SiNx are [0, π / 2] and [3 π / 2,2 π]
The increasing range of cosx is [π, 2 π]
So the same increasing function is [3 π / 2,2 π]
Sine function cosine function What is the increasing interval of the function y = 2Sin (2 π / 3, - 3 π)

1、sina=√5/3,cosa=2/3
2、sina=4/5,cosa=-3/5
3、sina=-1/2,cosa=﹣√3/2
4、sina=-12/13,cosa=5/13
The image of sine function and cosine function Given that the minimum value of function f (x) = 2sinwx (W > 0) on the interval {- π / 3 π / 4} is - 2, then what is the minimum value of W equal to?
