A Very Tanned Log

Geometry Level 1

Evaluate the sum

   logcos1(tan1)+logcos2(tan2)+logcos3(tan3)++logcos44(tan44)+logsin45(tan45)+logsin46(tan46)++logsin89(tan89).\begin{aligned} & \ \ \ \log_{\cos1}(\tan{1}) \\ &+\log_{\cos{2}}(\tan{2}) \\ &+ \log_{\cos{3}}(\tan{3}) \\& +\ldots \\ &+ \log_{\cos{44}} (\tan{44}) \\ &+ \log_{\sin{45}}(\tan{45}) \\ &+ \log_{\sin46}(\tan{46}) \\ &+\ldots \\ &+ \log_{\sin89}(\tan{89}). \end{aligned}

Note: All angles are in degrees, and be aware that the base changes from cos \cos to sin \sin.
