WebThe derivative of sine is cosine: d d x sin ( x) = cos ( x) To find d d x g ( x): Differentiate tan ( x) + 1 term by term: The derivative of the constant 1 is zero. Rewrite the function to be differentiated: tan ( x) = sin ( x) cos ( x) Apply the quotient rule, which is: d d x f ( x) g ( x) = − f ( x) d d x g ( x) + g ( x) d d x f ( x) g 2 ( x) WebNote that since tanx = cosxsinx , sinx = cosxtanx Explanation: sinx +2tanx = 0 cosxtanx +2tanx = 0 ... Prove that tanx = sinx+ 1 have only one solution in (−2π, 2π) You can use the formulas tanx = 1−t22t, sinx = 1+t22t where t = tan(x/2). Then the equation becomes 1−t22t = 1+t22t +1 that can be rewritten 2t+ 2t3 = 2t−2t3 + 1−t4 ...
