WebThe cosine function cosx is one of the basic functions encountered in trigonometry (the others being the cosecant, cotangent, secant, sine, and tangent). Let theta be an angle measured counterclockwise from the x … WebWe know that the maximum value of a cos θ + b sin θ + c is c + ( a 2 + b 2). Substituting a = 13 2, b = - 3 √ 3 2 and c = 3, we get, The maximum value = 3 + 169 4 + 27 4 = 3 + 7 = 10. Hence, Option ( C) is the correct answer. Suggest Corrections.
WebIn dot product we use cos theta because in this type of product 1.) One vector is the projection over the other. 2.) The distance is covered along one axis or in the direction of force and there is no need of perpendicular axis … WebSolve for ? cos (theta)=- ( square root of 2)/2. cos (θ) = − √2 2 cos ( θ) = - 2 2. Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. θ = arccos(− √2 2) θ = arccos ( - 2 2) Simplify the right side. Tap for more steps... θ = 3π 4 θ = 3 π 4. The cosine function is negative in the second ...
