WebJul 10, 2016 · $\begingroup$ Hi @Blue , that was a great explanation for the angle sum and difference equations for all angles between 0 and 90, but I still cant wrap around the jump from acute to obtuse angles. From the post, I understand that the idea of trig functions have extended beyond the first quadrant and acute angles, but the link in between is not fully …

WebFeb 27, 2012 · This video helps us to learn to find the trigonometric ratios of 0 and 90 degrees. WebThis is also the relationship between all the other cofunctions in trigonometry: tan (θ)=cot (90°-θ), sec=csc (90°-θ). One other way to think about the relationship between a function and its cofunction is to think about the unit circle: your x-distance is described by cos (θ), and your y-distance described by sin (θ).

WebNov 8, 2024 · I am confused about the Unit Circle explanation for the trigonometric ratios for angles greater than 90 degrees. It seems that for the first (top right) quadrant, $\sin(\theta)$ is equivalent to the y-coordinate, because $\sin(\theta)$ = opposite / hypotenuse $\sin(\theta)$ = opposite [hypotenuse is 1]
