Say you’re using the top tip of the house (5,6). This form is (x,y) you must transform it to (y,-x) which is (6,-5). It just means put y first and the opposite of x second.

Use the graph of y=sin2θ to find the value of sin 2θ for θ= pi/4 radians

aivan3 [116]

The graph of sin function is a curve as shown below:

Now, Sin 2Ф , where Ф = $\frac{ \pi } {4}$

or sin 2Ф = 2 × $\frac{ \pi } {4}$

or sin 2Ф = $\frac{ \pi } {2}$

Ans, sin π/2 = sin 180/2 = sin 90 = 1

Thus, the curve has maximum at 90.
