Trigonometry of obtuse angles
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. WebObtuse angles are between 90° and 180°, and it can make the trigonometry go a bit strange. On this page we’ll go over how to use SIN, COS and TAN with obtuse angles. To get these questions correct, you need to be able to realise when your answer is sensible and when it …
