Trigonometry is not only important to score high marks in mathematics but also in day-to-day life. Trigonometry starts with the most important functions of ratio and reciprocal. Trigonometric ratios are calculated only for right angled triangles Sine, cosine and tangent are the three main pillars ...

$\begingroup$ l'Hôpital's rule is easiest: $\lim\limits_{x\to0}\sin x = 0$ and $\lim\limits_{x\to0}x = 0$, so $\lim\limits_{x\to 0}\frac{\sin x}x = \lim\limits_{x\to 0}\frac{\cos x}1 = 1 $ $\endgroup$ –Joren Commented Oct 23, 2011 at 20:41 2...
By similar triangles, our change just just our original triangle, rotated and scaled. Original triangle (hypotenuse = 1): height = $\sin(x)$, width = $\cos(x)$ Change triangle (hypotenuse = dx): height = $\sin(x) dx$, width = $\cos(x) dx$ ...
√3/2 and the value of tan 30 degrees is 1/√3. q6 how to find the value of tan 30 with respect to sin and cos? tangent of an angle is equal to the ratio of sine and cosine of the same angle. therefore, tan 30 = sin 30/cos 30 we know that, sin 30 = ½ and cos 30...
