Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-stepGet an answer for '`f(x)=cosx , c=pi/4` Use the definition of Taylor series to find the Taylor series, centered at c for the function.' and find homework help for other Math questions at eNotessqrt2/2 As you can see in the table above, cos45^@ or cospi/4 radians is the same thing as sqrt2/2 An alternative way is looking at the unit circle: We know that the cosine of an angle is the x-value of a coordinate. At pi/4, we can see that the x-value is sqrt2/2. Therefore, cos(pi/4) = sqrt2/2 Hope this helps!#cos(pi/4+pi/3) = (sqrt2-sqrt6)/4# Explanation: In order to evaluate #cos(pi/4+pi/3)# we need to use the compound angle formula for cos: #cos(A+B) -= cosAcosB-sinAsinB#
