Also, if anyone knows a good place to help me with Trig Identities. I can remember all the identities, I just suck at seeing what to convert them into.
Just a site for tips and such is what I'm looking for. Thanks.
I just started college trig, I've been looking threw the book but can't find the method to this problem,
+8 cookies for who ever tells me what to do.An object is traveling around a circle with a radius of 10 centimeters. If in 20 seconds a central angle of 1/3 radian is swept out, what is the linear speed of the object?
So it travels 1/3 of a radian in 20 seconds?
If so its travelling at (1/3)/20 = 1/60 radians per second or one radian per minute.
Trig identities can be found here: Table of Trigonometric Identities
In case I haven't asked enough already... :P
I tried just makeing a triangle, with sides opposite = 1 and adjacent = 5, giving a hypotenuse of Sqrt26, so Sec would be... sqrt26/5...?Use Fundamental Trig Identities/ Complementary Angle Theorem to find
If tan^2(theta) = 5, find the exact value of sec^2(theta).
My final answer was 1/6 centimeters/minute... And yet I didn't get that good feeling you get from confidently answering a question...?
Thanks.
EDIT: I should have left it at 1/6 centimeters/SECOND, that makes much more sense...
