From the curve y = sin x, graph the function
y = `sin(pi/2 + x)` which is cos x

From the curve y = sin x, graph the function
y = `sin (pi/2 - x)` which is also cos x (refer trigonometry)

From the curve y = x, draw y = − x

From the curve y = x, draw y = 2x

From the curve y = x, draw y = x + 1

From the curve y = x, draw y = `1/2 x +  1`

From the curve y = x, draw 2x + y + 3 = 0

From the curve y = |x|, draw y = |x − 1| + 1

From the curve y = |x|, draw y = |x + 1| − 1

From the curve y = |x|, draw y = |x + 2| − 3

From the curve y = sin x, draw y = sin |x| (Hint: sin(−x) = − sin x)
