**TI92P*main ifÿRcofun ÿp¥Z Differentiate the following two cofunctions C¼(sin(x),x) C¼(cos(x),x) Do you see a relation between the derivatives? See if the pattern holds for the derivatives of the next two cofunctions C¼(tan(x),x) cot(x)=1/tan(x) : C¼(1/(tan(x)),x) Write down the relation between the derivatives of cofunctions Take the derivative of sec(x) C¼(1/(cos(x)),x) Use your pattern to predict the derivative of csc(x) C¼(1/(sin(x)),x) What is the relation between derivatives of cofunctions?൬
