How to find the angle between two vectors if dot product and cross product are given? Consider the vectors u = 2i - 3j + 7k and v = 3i + 2j - 4k. (a) Evaluate the dot product u \cdot v (b) Find the magnitude of vectors u and v (c) Find the acute angle t...
Related to this Question If theta = -7pi/4, find tan(theta). If theta = 8pi/3, find tan(theta). If VxW=(2,-3,5) and V*W=3, find tan(theta) where theta is the angle between V and W. If tan(\theta) = -\dfrac{3}{7}; \; 270^{\circ} \theta 360^{\...
sin 4530^@ = sin(25pi+pi/6) = sin(2**12pi+pi+pi/6) =sin(pi+pi/6) = sin210^@ So, 180^@ lt 210^@ lt 270^@. :. theta lies in 3rd quadrant.
If you used a numerical solver to find a solution, but in another approach, an analytical solution is found, then the numerical solver is never any better than the convergence tolerances applied. So one would generally prefer the analytical solution. If you are comparing two numerical metho...
(25)/7. Rearranging this equation results in sin(A) = sin(25)*12/7. Using a scientific calculator to find sin(25), carrying out the rest of the equation would show that sin(A) = 0.724. To find angle “A,” use the calculator to determine the inverse sine of 0.724. The answer ...

Hi, I am trying to find the radiuses of an airfoil. I extracted the data points from a design software (Catia) to Excel. Now, l have the points of the airfoil curve, but it is defined as splines. I need to redefine the airfoil as circles. Any help would be great....
ACOTtan(θ) = opposite/adjacent The trigonometric functions relate an angle expressed in radians or degrees to two out of three sides in a right triangle. What is the angle θ? The Greek letter theta (θ) is commonly used to represent an unknown angle in a right triangle. ...
