What is the range of the function y= 2sinx​
Nana76 [90]
<h2>Hello!</h2>

The answer is: [-2,2]

<h2>Why?</h2>

The range of a function shows where the function can exist in the y-axis.

To know the range of the function, we have to isolate x,

So

y=2sinx\\\frac{y}{2}=sinx\\ Sin^{-1}(\frac{y}{2}) = x

The only possible values that y can take go from -2 to 2. Taking values out of these values will give as result a non-real number.

Therefore,

The range of  the function is [-2,2]

Have a nice day!

Find the exact values of the indicated trigonometric functions. Write fractions in lowest terms.
vodka [1.7K]

For this case we have that by definition of trigonometric relations of a rectangular triangle, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. While the tangent of the same angle is given by the leg opposite the angle on the leg adjacent to the angle.

Then, according to the figure we have:

sin (B) = \frac {7} {25} = 0.28\\tg (B) = \frac {7} {24} = 0.2917

Answer:

sin (B) = \frac {7} {25}\\tg (B) = \frac {7} {24}
