use the formula sec A = 1/cos A and substitute θ =60 degrees for A to get sec60= 1/cos60. On the calculator, find cos 60 by pressing the "cos" function key and input 60 to get .5 and calculate the reciprocal 1/.5 =2 by pressing the inverse function key "x -1 " and ente...
hence proved. practice problems calculate the value of (1/2) cos 45° + tan 60° + (2/3) sin 30°. find the value of x if cos x = 2 sin 45° cos 45° – sin 30°. write the values of cos 30°, sin 30°, cos 90°, tan 45°, sin 45°, and sin 90°. frequently ...
By mastering these basic derivative rules, you’ll be well-equipped to differentiate a wide range of functions on the TI-89 calculator. In the next section, we’ll explore how to use the calculator’s derivative function to find derivatives more efficiently. So, let’s continue our derivative...
In general mathematics, a functional may refer to a function specifically produced from a set ofreal-valued functions.For example, a functional could be the maximum of a set of functions on theclosed interval[0, 1]. Abinary functionaltakes two sets of functions to create one function. For e...
Let us take some random values on both sides of the vertical asymptote x = 2 and calculate the respective y-values. xy -1 (-1+1)/(-1-2) = 0 (x-int) 0 (0+1)/(0-2) = -0.5 (y-int) 2 VA 3 (3+1)/(3-2) = 4 4 (4+1)/(4-2) = 2.5 Let us plot all these po...
