Question

How do you write an equation of `y=sinx` with pi units to the left?

Answer 1

See below.

Explanation:

Not exactly sure what you are asking here. If you mean translating the curve of sin(x) `pi` units to the left, then:

`y = sin(x+pi)`, will be the curve of `sin(x)` shifted `pi` units to the left.
