Question

How would I go about drawing the graph for
y = 3 - 2 tan (0.5x) for 0 12 years ago

Answer 1

why don't try plotting graph by plotting points first it would be a lot easy

Answer 2

okay there is another way

we will plot y=2tan(0.5x)

first now we know
at x=0 y=0

x=pi/2 we have y=2 and

at x=pi it touches to infinity (as it would be y=2(infinity) so it will be y=infinity )

so we will graph this as follows
