(a) z±i; (b) Rez 0.arrow_forward44 4. Write the function f(x)=2+ ANALYTIC FUNCTIONS 1 (z = 0) Z. in the form f(z) = u(r, 0) + iv(r, 0). Ans. f(z) = = (1 + ² ) cos+ir i ( r — 1 ) sin 0. r CHAP. 2arrow_forwardGiven the (3-2-1) Euler angle set (10,20,30) degrees, find the equivalent (3-1-3) Euler angles. All the following Euler angle sets are 3-2-1 Euler angles. The B frame relative to N is given through the 3-2-1 EAs (10,20,30) degrees, while R relative to N is given by the EAs (-5,5,5) degrees. What is the attitude of B relative to R in terms of the 3-2-1 EAsarrow_forward

Show that a set S is open if and only if each point in S is an interior point.arrow_forward
- 2. Derive the component transformation equations for tensors shown be- low where [C] = [BA] is the direction cosine matrix from frame A to B. B[T] = [C]^[T][C]T 3. The transport theorem for vectors shows that the time derivative can be constructed from two parts: the first is an explicit frame-dependent change of the vector whereas the second is an active rotational change of the vector. The same holds true for tensors. Starting from the previous result, derive a version of transport theorem for tensors.
