k what is the answer of the questio with tangent?
 one year ago

InspiredBest ResponseYou've already chosen the best response.3
Well 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

and 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)

pi/6 and pi/3 (take a look at the unit circle for the second one)
 one year ago

fgohBest ResponseYou've already chosen the best response.0
how 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?

Let's see. arctan (sqrt3/3) is the same thing as arctan (1/sqrt3) right? and using 306090 triangle, you have this: dw:1358819026253:dw

Anyway, 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.

but is is y/x right why it doesn't work
 one year ago

fgohBest ResponseYou've already chosen the best response.0
if u do it with the values on unit square and i thought the domain is from (pi/2,pi/2)?

\[COS ^{1}(\sin 11\pi/6)\]
 one year ago

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

InspiredBest ResponseYou've already chosen the best response.3
ok :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)
 one year ago

rudra333Best ResponseYou've already chosen the best response.0
is that the answer arccos(1/20)
