Find all angles x in degrees that satisfy each equation. Use k to represent any integer. PLEASE HELP

seriously cannot figure these out.. have 124 to do. PLEASE HELP

1) tan x = -1



2) f(x) = 5sin(x) + 1 for 0 <= x <= (pi/2)

1)

tan(x) = -1 -----> tan(45) = 1, therefore tan(-45) = -1

x = -45 + 180k

--------------------

2)

You don't say what to do here. There is no equation to satisfy. Instead we have a function, so any value of x is valid, and f(x) will depend on that value of x.

Also, f(x) is never 0 on the given interval.

What I can tell you is that for 0 ≤ x ≤ π/2 we have 0 ≤ sin(x) ≤ 1
Therefore 1 ≤ f(x) ≤ 6
