Answer:
Step-by-step explanation:
Given differential equation,
Characteristic equation is given by
.
Differential equation have repeated roots and solution of differential equation is .............................(1)
Initial conditions are
Plugging first condition in equation (1),
Equation (1) becomes
............................(2)
differentiate equation (2) with respect to 'x',
Plugging second condition,
Hence,
Check the picture below.
in the picture below, the bottom part
notice, 69° + 21° = 90°, so 21° and 69° are really complementary angles, sharing the same quadrant, meaning for any two sides of lengths say, a,b one angle will have a tangent of say b/a, then the other will have a tangent of a/b.
namely the tangent of each angle, is simply the other's tangent upside-down.
