Now substituting the value of $\cos \left( {{270}^{\circ }}+{{0}^{\circ }} \right)$ in equation (iii), we get $\cos \left( {{270}^{\circ }} \right)=0$ Hence, the cosine of 270 degrees is 0. For tangent of 270 degrees: We are well aware of the identity...
The line tangent to the circle x^2+y^2=1 at (35,45 ) is perpendicular to the radius drawn from the point of tangency.Note that the equation x^2+y^2=1 represents a circle centered at the origin with a radius of one unit.The line containing the radius from point (35,45 ) has...

例:What is the greatest prime factor of 2100 - 296? (A) 2(B) 3(C) 5(D) 7(E) 11例:A positive integer n is said to be “prime-saturated” if the product of all the different positive prime factors of n is less than the square root of n. What is the greatest two-digit pr...
In order to solve this question, we will first start by considering $y=\arctan x$. It is the same as $y={{\tan }^{-1}}x$. Now let us move the inverse tangent to the left side of the equation. By doing so, it will give us, ...
Trigonometric functions show the relationship between an angle to the ratio of two sides in a right triangle. The six trigonometric functions are sine, cosine, tangent, secant, cosecant, and cotangent. Answer and Explanation:1 Solve the the value ofy, in the equation, ...
