10.4 Graphing of Trigonometric Functions 三角函数的图像

Sketch the graph of the following functions for the given range of x.

在指定的x范围，画出下列各函数的图像

(1) $y = sin3x$

$0^{\circ} \leq x \leq 360^{\circ}$

(2) $y = 2cosx$

$-360^{\circ} \leq x \leq 360^{\circ}$

(3) $y = \frac{1}{2}sin3x$

$-180^{\circ} \leq x \leq 180^{\circ}$

(4) $y = cos2x-1$

$0 \leq x \leq 2\pi$

(5) $y = | sin2x |$

$-360^{\circ} \leq x \leq 360^{\circ}$

(6) $y = 2 - cos x$

$-2\pi \leq x \leq 2\pi$

(7) $y = cos (x+\frac{\pi}{4} )$

$0 \leq x \leq 2\pi$

(8) $y = sin (x-\frac{\pi}{2} )$

$0 \leq x \leq 2\pi$

(9) $y = cos (2x-\frac{\pi}{2} )$

$0 \leq x \leq 2\pi$

(10) $y = 2sin (3x+\pi )$

$0 \leq x \leq 2\pi$
