B i l sin theta
WebHere are some trigonometric relationships that can be found by playing around with the unit circle: sin (pi-θ)=sin (θ) cos (pi-θ)= -cos (θ) sin (θ+pi)= -sin (θ) cos (θ+pi)= -cos (θ) cos (θ+pi/2)= -sin (θ) sin (-θ)= -sin (θ) cos (-θ)=cos (θ) I hope these relationships help you in trig! 12 comments ( 153 votes) Upvote Flag Show more...

Did you know?
WebJul 9, 2012 · hey Studiot , thank you for your reply , it solved most of my difficulties but i still have a confusion. in first quadrant , we get cos theta = x/underoot x^2 + y^2. but then if we do it for 90+theta .. my value for sin (90 + theta) is -x/underoot x^2 + y^2. which is basically our previous value of cos theta * (-) therefore sin 90 + theta ... Web2. Start with Then your equation becomes or It's a bit easier if we assume initial conditions, say and , so that Then so that or This equation is of the form . Your solution is given by . That's about as much as you need to know, since it's more efficient to just solve the original equation numerically.

WebMar 13, 2016 · Explanation: using appropriate Addition formula. ∙ sin(A± B) = sinAcosB ± cosAsinB. hence sin( π 2 − θ) = sin( π 2)cosθ − cos( π 2)sinθ. now sin( π 2) = 1 and cos( π 2) = 0. hence sin( π 2)cosθ − cos( π 2)sinθ = cosθ − 0. ⇒ sin( π 2 −θ) = cosθ.
