1 Subtract the vector (-1, -2, 1) from the vector (-3, 0, 1) 2 Consider the vector in and la with the componentin - (1,1, 3) and b- (-1, 2, 1). Answer the following questions to find the angle [in degrees) between the vectors What is the scaler product of a and bl What is the length of the vector a? What is the length of the vector b? What is the value of cos ? The angle in degrees is 0 = 3 Simplify the given expression as a single sin angle: sin(3x + a) (a is an unknown angle, put any angle variable in your answer in brackets e.g. cos(a), sin(a)) 4 Consider the vector (2, -2, 1). What is the length of this vector = Enter your answer exactly, using the squt function for square roots if necessary, for example inputting v/3 as sart(3). What is the unit vector in the direction of the vector S Solve the equation - Inz = In 2 - Inx2. Enter your answer as a fraction if needed i.e. 9 143 as 9/143 and not as a decimal. Evaluate: log 64 7 Simplify the expression: COS sin (7) = Solve the inequality 103
