how do I solve : SEC1035

Question

anonymous · Answer

sec1035 = $$1/\cos 1035$$
 
Can you solve it from there?

anonymous · Answer

no can you explain more..? sorry ;P

phi · Answer

is that 1035 degrees?

anonymous · Answer

yes

phi · Answer

Everytime you go 360 degrees you are back where  you are started.
So you have to divide by 360 and use only the remainder.

anonymous · Answer

okay so it's Sec315*. what do I do now?

phi · Answer

I would do cos(315) and then flip it after I get the answer
secant(x)= 1/cos(x)

anonymous · Answer

Secant is the reciprocal of cosine, so you take 1/cos315.|dw:1315446365930:dw|

anonymous · Answer

Cosine is x/r, so the x would be $$\sqrt{2}$$, and since you are on a unit circle, the radius (r) would be 1.

anonymous · Answer

(Because the angle of 315 degrees creates a 45-45-90 triangle.)

anonymous · Answer

so answer would be root(2)?

phi · Answer

conquers should memorize
cos(45) = sin(45) = sqrt(2)/2
also sin(30)= 0.5
 cos(30)= sqrt(3)/2

anonymous · Answer

Right! Do you understand how that works?

anonymous · Answer

yes yes ! :D! oh god. sorry for making you elaborate all these, thank you guys!

anonymous · Answer

I enjoy it! You're very welcome. :]
