Web4.1 Version 3 Answers. 1. Sketch the graph of f by hand and use your sketch to find the absolute and local maximum and minimum values of f. (If an answer does not exist, enter DNE.) f (t) = 3 cos t, -3pi/2 <= t <= 3pi/2. 2. Sketch the graph of f by hand and use your sketch to find the absolute and local maximum and minimum values of f. WebAnalysis. This answer looks quite different from the answer obtained using the substitution x = tanθ. To see that the solutions are the same, set y = sinh−1x. Thus, sinhy = x. From …
WebSpecify a function of the form x = funx(t). The function must accept a vector input argument and return a vector output argument of the same size. Use array operators instead of matrix operators for the best performance. For example, use .* (times) instead of * (mtimes). Example: funx = @(t) sin(2*t); WebLearning Objectives. 1.3.1 Convert angle measures between degrees and radians.; 1.3.2 Recognize the triangular and circular definitions of the basic trigonometric functions.; 1.3.3 Write the basic trigonometric identities.; 1.3.4 Identify the graphs and periods of the trigonometric functions.; 1.3.5 Describe the shift of a sine or cosine graph from the …
