10 maj 2016 · We have $\cos2x=\sin x=\cos\left(x-90^{\circ}\right)$. So $2x=\pm\left(x-90^{\circ}\right)+k\cdot360^{\circ}$. Working out $2x=x-90^{\circ}+k\cdot360^{\circ}$ under condition $0^{\circ}\leq x\leq360^{\circ}$ leads to $x=270^{\circ}$.

Using the 45-45-90 and 30-60-90 degree triangles, we can easily see the relationships between \sin x sinx and \cos x cosx by the lengths they represent. The several \cos 2x cos2x definitions can be derived by using the Pythagorean theorem and \tan x = \frac {\sin x} {\cos x}. tanx = cosxsinx. Double Angle Formulas.
We can find the missing angles and missing sides of a right-angled triangle with the help of trigonometric ratios. In a right-angled triangle, one angle is 90 degrees, and the other two angles are 45 degrees each. The three sides of a right-angled triangle are. Hypotenuse: Hypotenuse is opposite to 90 degrees and is the longest side of the ...
Find all possible exact solutions for the equation cosθ=12.cosθ=12. Find all possible exact solutions for the equation sint=12.sint=12. Given a trigonometric equation, solve using algebra. Look for a pattern that suggests an algebraic property, such as the difference of squares or a factoring opportunity.
