Best ResponseYou've already chosen the best response.31) For dot product there is a system. X is a vector we need to find: \(\overrightarrow u \cdot \overrightarrow x=0\) \(\overrightarrow v\cdot \overrightarrow x=0\) Here you have 2 equations and 3 variables (components of X). 2) Every vector that is perpendicular on any two vectors has the same direction as the cross product of these two vectors. So: \(\overrightarrow x=\alpha (\overrightarrow u\times\overrightarrow v) \)

Best ResponseYou've already chosen the best response.3All you have to know to solve your problem is to know formulas for dot and cross products and read above.

Best ResponseYou've already chosen the best response.0Ok so for the dot product I will get a parametric equation?
