WebIf a b a ¯. b ¯ = 3 and a b i j k a ¯ × b ¯ = 2 i ^ + j ^ + 2 k ^, find the angle between a a ¯ and b b ¯. Advertisement Remove all ads Solution Let θ be the angle between a a ¯ and b b ¯ ∵ a b i j k a ¯ × b ¯ = 2 i ^ + j ^ + 2 k ^ ∴ a b a ¯ × b ¯ = 2 2 + 1 2 + 2 2 = 4 + 1 + 4 = 3 ∴ a b a ¯ b ¯ sin θ = 3 ... (1) ∴ a b a ¯. b ¯ = 3 WebAxB= absin (theta) A.B= abcos (theta) From given conditon it follows. sin (theta)= root3cos (theta) which means theta is 60. For getting A+B we need magnitudes of these vectors … pine creek properties ohio

WebNow we can show that to check B = A − 1, it's enough to show AB = I n or BA = I n. Corollary (A Left or Right Inverse Suffices) Let A be an n × n matrix, and suppose that there exists an n × n matrix B such that AB = I n or BA = I n. Then A is invertible and B = A − 1. WebClick here👆to get an answer to your question ️ If ( a × b)^2 + ( a· b)^2 = 144 and a = 4 , then b is equal to WebIf a → and b → are unit vectors, then find the angle between a → and b → given that ( 3 a → − b →) is a unit vector.
