Question

Tan x degrees = 0.3, find the value to the nearest tenth

Answer 1

Do you have a calc?

Answer 2

yes

Answer 3

arctan(tan(x)) = arctan(0.3)
x = arctan(0.3)

Answer 4

tan^(-1) on your calculator is arctan

Answer 5

they usually refer to the inverse of tan as arctan and not tan^(-1) because tan^(-1) looks like tan to the negative exponent 1 or 1/tan(x)

Answer 6

fyi, i think calculators just use tan^(-1) to save room
