WebWithout using trigonometric tables find the values of: cos70°/sin20° + cos57°cosec33°-2cos60° Open in App. Solution. Here is the solution for your question, cos 70/sin 20+cos 57 x cosec 33 - 2cos 60 We know that cos (90-x)= sinx Therefore,cos 70=cos (90-20)=sin 20 WebEach operation does the opposite of its inverse. The idea is the same in trigonometry. Inverse trig functions do the opposite of the “regular” trig functions. For example: Inverse sine. ( sin − 1) (\sin^ {-1}) (sin−1) left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis. does the opposite of the sine.
