Question

What is cos(36×log(82×ln(54,569×cos(1÷5,693

Answer 1

In order to solve the given expression, one must set the calculator up in Radians. Then:

`\begin{gathered} \cos \mleft(36* log(82* ln(54,569* cos((1)/(5,693)\mright)))=\cos (36* log(82* ln(54,569* cos(0.1756))) \\ =\cos (36* log(82* ln(54,569*0.9846))=\cos (36* log(82* ln(53.7293)) \\ =\cos (36* log(82*3.9840))=\cos (36* log(326.6846))=\cos (36*2.5141) \\ =\cos (90.5086)=-0.8267 \end{gathered}`

Therefore the final result is -0.8267.
