Webb16 nov. 2024 · I have to find the range of f ( x) = sin ( x) cos ( 2 x). Here's what I have so far: f ′ ( x) = − cos ( x) cos ( 2 x) − 2 sin ( 2 x) sin ( x). So cos ( x) cos ( 2 x) + 2 sin ( 2 x) sin ( x) = cos ( x) ( 2 cos 2 ( x) − 1) + 4 sin 2 x cos x = 0 . Hence cos ( … WebbThe three common trigonometric substitutions are the restricted sine, restricted tangent and restricted secant. Thus, for sine we use the domain [−π/2, π/2] [ − π / 2, π / 2] and for tangent we use (−π/2, π/2). ( − π / 2, π / 2). Depending on the convention chosen, the restricted secant function is usually defined in one of two ... WebbInverse hyperbolic functions. If x = sinh y, then y = sinh-1 a is called the inverse hyperbolic sine of x. Similarly we define the other inverse hyperbolic functions. The inverse hyperbolic functions are multiple-valued and as in the case of inverse trigonometric functions we restrict ourselves to principal values for which they can be considered as single-valued. options360 reviews

There is a simple horizontal rule for determining whether a function $y=f(x) $ is one-to-one: $f $ is one-to-one if and only if every horizontal line intersects the graph of $y=f(x) $ in the $xy$-coordinate plane at most once (see Figure 5.3.3).

Alpha is pattern matching, using sec − 1 ( sec ( x)) = x, which is true for most x. It is often sloppy on cases like this. Ross is correct. To expand, Wolfram is probably doing something like this: It notices that you are calling f − 1 ( f ( x)).
