## Direction cosine of x axis given direction ratio of x, y and z axis Solution

STEP 0: Pre-Calculation Summary
Formula Used
direction_cosine_1_with_respect_to_x_axis = (Direction Ratio 1)/sqrt((Direction Ratio 1)^2+(Direction Ratio 2)^2+(Direction Ratio 3)^2)
l1 = (a1)/sqrt((a1)^2+(b2)^2+(c3)^2)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Direction Ratio 1 - Direction Ratio 1 is ratio proportional to direction cosine w.r.to x axis. (Measured in Hundred)
Direction Ratio 2- Direction Ratio 2 is ratio proportional to direction cosine w.r.to y axis.
Direction Ratio 3 - Direction Ratio 3 is ratio proportional to direction cosine w.r.to z axis. (Measured in Hundred)
STEP 1: Convert Input(s) to Base Unit
Direction Ratio 1: 0.7 Hundred --> 0.7 Hundred No Conversion Required
Direction Ratio 2: 0.2 --> No Conversion Required
Direction Ratio 3: 0.5 Hundred --> 0.5 Hundred No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
l1 = (a1)/sqrt((a1)^2+(b2)^2+(c3)^2) --> (0.7)/sqrt((0.7)^2+(0.2)^2+(0.5)^2)
Evaluating ... ...
l1 = 0.792593923901217
STEP 3: Convert Result to Output's Unit
0.792593923901217 Hundred --> No Conversion Required
0.792593923901217 Hundred <-- Direction cosine 1 with respect to x axis
