Orthogonal polynomials(also called anorthogonal polynomial sequence) are a set of polynomials that are orthogonal (perpendicular, or at right angles) to each other. As a simple example, the two-dimensional coordinates {x, y} are perpendicular to each other. So two polynomials that each fit along...
If you find that many question types take more than that minute or even a few questions take more than 90 seconds to answer, consider a new approach to those questions during your practice. Come at similar questions from different angles or rework the same question with alternate methods until...
Referring to kuruman's first post, unfortunately the angles in this task are rather large, between 30 to 80 degrees (approximately). But they are smaller than 90 deg. Then the equality does not hold. See post #4. Likes Philip Robotic Nov 5, 2018 #7 Philip Robotic...
