What are the sin, cos, and tan buttons on my calculator for? (And how do they work?) When might I ever actually want to calculate the sine or cosine something? Those, obviously, are all very important (and very reasonable) questions to ask. And they’re also very important questions t...

Sine (sin) and cosine (cos) are fundamental trigonometric functions that play a vital role in various areas of mathematics, physics, and engineering. The sine of an angle in a right-angled triangle is defined as the ratio of the length of the side opposite the angle to the length of the...

sin(cos(x))? Question: What is sin(cos(x))? Trigonometric Functions: Trigonometry is the branch of mathematics which are used widely in many real life calculations, specially in construction purposes. The functions used relate the angle to numerical values sinx and cosx are ...
How do the derivatives of cos and cosh differ? The derivative of cos is -sin, reflecting the sine function with a negative sign, whereas the derivative of cosh is sinh, or the hyperbolic sine function. 6 What are the inverse functions of cos and cosh? The inverse of cos is arccos, whi...

$\cos \left( {{270}^{\circ }} \right)=0$ Hence, the cosine of 270 degrees is 0. For tangent of 270 degrees: We are well aware of the identity that $\tan \theta =\dfrac{\sin \theta }{\cos \theta }$ Thus, we can write ...
So this leads us to the question that since some behaviours are criticised, are there any which areabovecriticism or are sacrosanct and on what basis do we decide this? What I am getting at, is that do we as a society think that criticising, say, homosexual behaviour or something like pa...
