Web1 Determine the angle between vectors a and b ( a ≠ 0, b ≠ 0) if a + 3 b is perpendicular to 2 a − b and a + 7 b is perpendicular to 2 a + b. I've done this: ( a + 3 b) ⋅ ( 2 a − b) = 0 … 5 a ⋅ b = 3 b ⋅ b − 2 a ⋅ a ( a + 7 b) ⋅ ( 2 a + b) = 0 ⋯ 15 a ⋅ b = − 2 a ⋅ a − 7 b ⋅ b which gives me: a ⋅ b = ( − ( b ⋅ b + a ⋅ a)) / 5 WebFind a . b if a = 4, b = 9, and the angle between a and b is pi / -6 radians. Let a = 3i + 5j - 4k and b = i + j - 3k. Find the angle (in radians) between a \times b and b. Find the …

WebTrigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation … WebLet's try the best Express the following angles. Express the following angles in radians (a) 45 Apps can be a great way to help students with their algebra.
