Question

can any smart person help me with my calculus

Answer 1

calc 1, 2 or 3?

Answer 2

calc 1 unit circle finding the inverse function

Answer 3

post the question

Answer 4

Arccos(cos(-4\[\pi\] /3))

Answer 5

Cos and arccos are inverse functions.. so they cancel each other out, and you'll just end up with whatever u had in the parenthesis

Answer 6

ok how about Arcsin(cos(\[\pi\]/4

Answer 7

Cos(pi/4)=sqrt(2)/2
ArcSin(Cos(pi/4)) = ArcSin(sqrt(2)/2)

Answer 8

Sin of what angle is sqrt(2)/2?

Answer 9

lol i have a feeling i might be creepin u out with my pic haha

Answer 10

pi/4 rite lol i have see creeper photos dont worry

Answer 11

yes haha, and lol that wasn't me

Answer 12

so wat does \[\theta\]=arctan 1 mean

Answer 13

Tangent of what angle is 1?

Answer 14

idk

Answer 15

Come on, tangent = 1, that means Sin/Cos=1, that means Sin = Cos. Both sin and cos of pi/4 are sqrt(2)/2

Answer 16

ok im having a quiz tommorrow so if my teacher as me to evalute Arccos 1/2 in to radians what do i do

Answer 17

Cos of what angle in degrees is 1/2?

Answer 18

pi/3 rite?

Answer 19

i think it's pi/6.. hold on i'll show u a trick how to memroize them all

Answer 20

ok

Answer 21

http://www.twiddla.com/756482 go on there

Answer 22

but pi / 3 and pi/6 both have 1/2 in the coordinates?

Answer 23

Cos^(-1) [1]. Which angle's cosine is 1? Angle = 0

Answer 24

oh

Answer 25

so you would do the same for cos\[\Lambda ^{^{-1}}\left( -1 \right)\]

Answer 26

I don't get that question

Answer 27

cos exponent -1(-1)

Answer 28

i think its 180

Answer 29

Yes, Cos exponent -1 (-1) means inverse cos of (-1), cos of what angle is -1? It is 180, which is pi in radians

Answer 30

ok im getting it a little so then wat would u do for tan exponent -1 (-1)

Answer 31

tangent of what angle is -1?

Answer 32

sorry dont know

Answer 33

-pi/4

Answer 34

oh ok but wat if they ask you to do sin expontent -1 sqrrot of 2 /2 but the sqrrot appears twice so it between 3pi/4 or pi/4 how do you know wat to choose
