Best ResponseYou've already chosen the best response.0k what is the answer of the questio with tangent?

anonymous

Best ResponseYou've already chosen the best response.0Well it's just the inverse of cos(0). Cos(0) =1. The inverse of that switches the values of the sine cosine functions. cos(90) gives you 1. but because remember, sin(0)=0 and sin(90)=1

Best ResponseYou've already chosen the best response.0and an easy way to remember is: sin is your y axis and cos is your x axis. the inverse of a function is basically switches the x and y. what was y=f(x) is now x=f(y)

Best ResponseYou've already chosen the best response.0pi/6 and pi/3 (take a look at the unit circle for the second one)

Best ResponseYou've already chosen the best response.0how did u get pi/6? i know in the unit cirlce but when i tried all of them tan is y/x then which onw will work?

Best ResponseYou've already chosen the best response.0Let's see. arctan (sqrt3/3) is the same thing as arctan (1/sqrt3) right? and using 306090 triangle, you have this: dw:1358819026253:dw

Best ResponseYou've already chosen the best response.0Anyway, since the value is negative, it will occur in the 2nd or 4th Quadrant. Since we want a single value, you usually use the 4th quadrant, and that gives you a negative value.

Best ResponseYou've already chosen the best response.0and which one do u do first?

anonymous

Best ResponseYou've already chosen the best response.0ok :0 sin(11pi/6) is the same thing as sin(12pi/6pi/6) so you get sin(2pipi/6) > sin(pi6)=1/2 and so you have arccos(1/2)

Best ResponseYou've already chosen the best response.0is that the answer arccos(1/20)
