Question

true or false for angle Θ between 0 and π/2. if tanΘ=(1/3), then sinΘ = (√10)/10.

Answer 1

Theta = arctan(1/3) = 0.32175...
Theta = arcsin(sqrt(10)/10) = 0.32175...

Answer is true

Answer 2

this one is a tricky and easy way to solve the problem

Answer 3

i think i need the easy way because we haven't covered arctan yet lol

Answer 4

arctan = tan^(-1) (1/3)

Answer 5

or 1/tan(1/3)

Answer 6

is that the only way to solve it?

Answer 7

i tried to solve for cosΘ and got 3√10/10.

Answer 8

well i tryed to go your way but i cant go anywhere... Im afraid the only solution i can gave you to this problem is the one i already gave you
