	0 answers Post by Ron Weldy on February 25, 2011 I have a problem that looks like y=1+2sinx;x=pie/6 I'm not sure what to do

	0 answers Post by Nicolette Reilly on November 17, 2011 how do you find the derivative of f(x)=cos (pi/x) ?
	0 answers Post by Stefán Berg Jansson on November 25, 2011 I try to help out, no promises tho... It will be good practice for me. @Ann Cea When she factored out x. If we think about it seperatly and factor only csc(x)2x, we get the following. csc(x)2x = csc(x)2x = x(csc(x)2) = x(2csc(x)) @Ron Weldy on February 25 at 09:21:47 AM If it is only plugging in x then, y=1+2sinx;x=pie/6 y=1+2sin(pi/6) y=1+20,5(sin(pi/6) = 0,5) y=1+1 = 2 If you were suppose to take the derivative first and then plug in x: y'=2cos(x) (1' = 0 and 2sin' = 2cos) Plug in pi/6 where x is 2cos(pi/6)= 2(sqrt(3)/2) = sqrt(3) @Nicolette Reilly f(x)=cos(pi/x) I will use the cain and the quotient rule. First I will use the cain rule and get: cos'(pi/x)(pi/x)' = -sin(pi/x)(pi/x)' Then I will use the quotient rule on (pi/x)' and then multiply it with -sin(pi/x) -sin(pi/x)(0x-pi1)/x^2= (-sin(pi/x)*-pi)/x^2 = sin(pi/x)pi/x^2 Hope I did not make any mistakes.. I often do

Trigonometric Derivatives

You should memorize these formulas – they are important!
The derivation of the results for and is famous and involves a couple famous limits.
One type of problem here simply incorporates trigonometric functions into differentiation problems involving, for example, the Chain Rule.
You can use the derivative formulas for and to derive the derivative formulas for the other trigonometric functions.
