[5 marks] A linear combination B perpendicular C coincident D the scalar form E the normal F direction vector G resultant H projection I parallel i) A vector quantity created by adding two vectors. ii) The use of scalars and vectors to produce one vector in terms of others. iii) [A, B, C] from the Cartesian form of a plane is called iv) When the intersection of two lines results in many solutions. v) The resolution of one vector onto another vector. 23. Calculus. Fill in the blanks using the correct answer using words. The length of the blank does not reflect the length of the answer. [10 marks] A negative to zero to positive B concave down C slowing down D is increasing E optimization F endpoints G positive to zero to negative H second derivative I midpoint J point of inflection K is decreasing L continuous M maximum point N cusp 0 differentiable P critical numbers Q concave up R first derivative Answers to Calculus Word Bank Go Here. (Answers may be repeated). a) A function is on an interval if the second derivative is positive on that interval. b) The is sometimes called rate of change of the slope of the tangent. C) If f" (a) = 0 and f"(x) changes sign at x = a, there is a at (a, f(a)) d) If f'(x) changes from as x increases from x a, then (a, f (a)) is a local minimum value. e) The absolute maximum or minimum values can often be found at the of an interval. f) If you are looking at the graph of f'(x) over an interval, and its slope is always negative, then you can say that f (x) is over that interval. g) If h(x) = f(x)g(x), where f(x) and g(x) are functions, then h'(x) = f' (x)g(x) +f(x)g'(x) h) An object is if v(t) x a(t)
