16\.\* Show that a. sin( π 2 + iy) = 1 2 (ey + e−y ) = cosh y b. |sin z| ≥ 1 at all points on the square with vertices ±(N + 1 2 )π ± (N + 1 2 )πi, for any positive integer N. c. |sin z|→[infinity], as Imz = y → ±[infinity].

What are correct trigonometric ratios that could be used to determine the length of ln

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Given a: b and b: c, find a: b: c. write the ratio in simplest form. a: b=6: 10 and b: c=21: 33
