The Organic Chemistry Tutor 287,484 views. For such simplifications, it is usually convenient to convert any trigonometric function that is not sine or cosine, into sine or cosine. In this case, you have: sin theta / sec theta = sin theta / 1/cos theta = sin theta cos theta.
Free math lessons and math homework help from basic math to algebra, geometry and beyond. Students, teachers, parents, and everyone can find solutions to their math problems instantly. Using complementary angle formulas,we have sintheta = cos90°- theta costheta = sin90°-theta sectheta = cosec90°-theta cosectheta = sec90°-theta. We can prove this from left hand side as well as right hand side.
28/01/2010 · \\displaystyle Cos\theta\ in a unit circle gives the x co-ordinate of a point on the circumference. \\displaystyle Sin\theta\ gives the y co-ordinate of the same point. \\displaystyle -Sin\theta\ is the negative of the y co-ordinate. To be equal. 29/09/2011 · 0 degrees to 360 degrees. please show me how! They are mathematical functions. Most people are introduced to them as trigonometric functions. In the context of a right angled triangle, with one of its angles being theta, Costheta = The ratio of the lengths of the adjacent side and the hypotenuse. Sintheta = The ratio of the lengths of the opposite side and the hypotenuse. More advanced.

How do you solve 3- 3 Cos theta = 2 Sin^2 theta? Trigonometry Trigonometric Identities and Equations Solving Trigonometric Equations. 1 Answer. Cos Theta is one of the six trigonometric functions. It is defined by the ratio of the adjacent side to the hypotenuse of the triangle where theta is an acute angle.
29/03/2015 · It's hard to know what kind of proof you would be satisfied with without knowing what you do know about this problem. Do you, for example, know that the line through the origin making angle \\displaystyle \theta\ with the x-axis crosses the unit circle at \\displaystyle cos\theta, sin\theta\? Let theta = x. sin xcos x=1/5. Dividing both sides by cos x. tan x1 = 1/5.sec x. or tan^2x2.tan x 1 =1/25.sec^2x. or 25tan^2x50tan x25 = 1 tan^2x. or 24 tan^2x 50tan x 24 = 0. or 12tan^2x 25.tan x 12 = 0. or 12 tan^2 x 16.tanx 9t. 30/04/2013 · I honestly have no idea how to solve this. I know the idea is to get the equation for there to be only one identity but I can't figure out how to do it. Also, theta is between 0 and 2pi. Thanks.
08/09/2006 · Hey, I’ve got a test in one week’s time and was studying through my text book of geometry and trigonometry. I came across a “rule” which shows how to simplify expressions in the form of [tex]a \cos \thetab \sin \theta[/tex] but I do not understand how this “rule” works. Can we solve $\cos\theta - \sin 2\theta\cos 3\theta - \sin 4\theta = 0$? Add to your resource collection Remove from your resource collection Add notes to. 13/04/2008 · sin 45 deg - theta = sin 90 - theta cos theta = sin 90 - theta 45 - theta = 90 - theta. 45 = 90. no solution is possible for this question. think about this. this kinds always result in an equation in terms of tan. you have cos theta on both sides and sin/cos =tan. what can you do with that annoying cos on the other side? 0.

I'm given the problem $\sin^2\theta\cos\theta = 2$ and I'm told to use the pythagorean identity $\sin^2\theta\cos^2\theta = 1$ to solve it. I end up with $\cos^2\theta - \cos\theta1 = 0$, but I know that's not going to factor and solve very nicely. Did I do something wrong, or is the answer going to end up being very ugly? Section Solution from a resource entitled Can we write $\sin\theta$ and $\cos\theta$ in terms of $\tan\theta/2$.
