Q 36. In exercise, letg1(t)=sint,聽g2(... [FREE SOLUTION]

Chapter 12: Q 36. (page 917)

In exercise, let
$g_{1} (t) = \sin t, g_{2} (t) = \cos t, g_{3} (t) = 1 - t, f_{1} (x, y) = x^{2} + y^{2}, f_{2} (x, y) = \frac{x^{2}}{y^{2}}, f_{3} (x, y, z) = \frac{x + y}{y + z}, r_{1} (t) = 鉄� 1 + t, t - 1 鉄�, r_{2} (t) = <t, t^{2}, t^{3}>$
Either simplify the specified composition or explain why the composition cannot be formed.
$r_{2} (f_{3} (x, y, z))$

Short Answer

Expert verified

Answer is $<\frac{x + y}{y + z}, {(\frac{x + y}{y + z})}^{2}, {(\frac{x + y}{y + z})}^{3}>$

Step by step solution

Step 1. Given information

$g_{1} (t) = \sin t, g_{2} (t) = \cos t, g_{3} (t) = 1 - t, f_{1} (x, y) = x^{2} + y^{2}, f_{2} (x, y) = \frac{x^{2}}{y^{2}}, f_{3} (x, y, z) = \frac{x + y}{y + z}, r_{1} (t) = 鉄� 1 + t, t - 1 鉄�, r_{2} (t) = <t, t^{2}, t^{3}>$

Step 2. Explanation

$\begin{array}{rcl} r_{2} (t) & = & <t, t^{2}, t^{3}> \\ f_{3} (x, y, z) & = & \frac{x + y}{y + z} \\ r_{2} (f_{3} (x, y, z)) & = & r_{2} (\frac{x + y}{y + z}) \\ = & <\frac{x + y}{y + z}, {(\frac{x + y}{y + z})}^{2}, {(\frac{x + y}{y + z})}^{3}> \end{array}$
