What is the value of tanx + cotx? | Socratic C is the correct answer You need to put on a common denominator This will be sinxcosx =(sin^2x + cos^2x) (sinxcosx) Applying the identity sin^2x + cos^2x = 1: =1 (sinxcosx) Now, recall that 1 sintheta = csctheta and 1 costheta = sectheta =cscxsecx So, C is the answer that corresponds Hopefully this helps!
If y=2x+tanx, find y third derivative of y? - Socratic If #y=2x+tanx#, find #y'''# third derivative of #y#? Calculus Graphing with the Second Derivative Relationship between First and Second Derivatives of a Function 1 Answer
What is the first differential of #Y=(2+tanx)logx# - Socratic (dY) dx= (2+tanx) x+lnxsec^2x [Given assumptions stated below] First a couple of assumptions on this question: (i) you are looking for the first derivative ((dY) dx) (ii) log is natural log (ln) Then, applying the Product Rule and standard differentials for lnx and tanx: (dY) dx= (2+tanx)* d dx(lnx) + lnx* d dx(2+tanx) = (2+tanx)* 1 x+lnx*(0+sec^2x) = (2+tanx) x+lnxsec^2x
