Question

For which value of θ is tan θ equal to sin θ?
A. pi
B. pi/2
C. pi/4
D.pi/6

Answer 1

do you have any idea ?

Answer 2

I have no idea on this one..@Ogzii

Answer 3

so , you know how to draw the Trigonometric circle ?

Answer 4

hang on I'm trying to figure it out. But in prior experiences I do not know how to draw a Trigonometric circle

Answer 5

anyway , you need to memorize some values of the angles , for example Cos p = -1
sin p = 0
now to find θ , you need to find this , cos θ = sin θ
cos θ - sin θ = 0

Answer 6

that equals out to 2pi

Answer 7

Cos-1 θ = 45
Sin-1 θ = 45
θ = 45 that simple

Answer 8

So the answer is pi/2? @Ogzii

Answer 9

nuh , 180 / 45 = 4
Pi / 4 is the angle
