Find the amplitude (if one exists), period, and phase shift of the function. Graph th function. Show at least two periods. \( y=2 \sin (\pi x+1)-2 \) What is the amplitude? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The amplitude is (Simplify your answer. Type an exact answer, using \( \pi \) as needed. Use integers or fractions for any numbers in the expression.) B. The function does not have an amplitude.

\( \tan \theta=-\frac{3}{4} \), given that \( \theta \) is in quadrant IV

Дан треугольник \( A B C \), в котором \( \angle A+\angle B=90^{\circ} \), а \( \sin B=\frac{2 \sqrt{5}}{10 \sqrt{10}} \) Найди \( \cos ^{2} B \).

As part of her assignment, Devi has to use her clinometer to measure the height of an office tower \( T A \). From a point \( B \), she observes that angle \( T B A=34^{\circ} \). She then walks 25 m away from the office tower to a point \( C \) and observes that angle \( T C A=26^{\circ} \). Find the height of the sfice tover.

\( \tan \theta=\frac{8}{15} \), given that \( \theta \) is in quadrant III

\( 2 \cos ^ { 2 } x - 1 \geq 0 \)
