How do you know if a graph is sin or cos? A parent graph of the sine function with no transformations starts at (0,0) and a parent graph of the cosine function with no transformations starts at (0,1) If there is a phase shift of 90 degrees or 2pi of either graph the two will...
Using tan x = sin x / cos x to Help If you can remember the graphs of the sine and cosine functions, you can use the identity above (that you need to learn anyway!) to make sure you get your asymptotes and x-intercepts in the right places when graphing the tangent function. At x...

What is the amplitude of y(x) = −2cos(x)?For this function, the value of the amplitude multiplier A is −2, so the amplitude is: amplitude: 2 ...and, by the way, the graph of y = −2cos(x) would also be flipped upside down, because of the "minus" sign....
sin(x) x^2 abs(x) x^2+2x+6 Plot polar equations by using the x and y variables. 2θ sin(2θ) Plot 3D functions by using the x and y variables. cos(x)+sin(y) x^2+y^2 Graph multiple functions by separating each equation with a comma. sin(x),cos(x) x,x^2,x^3 The...
The EE button on some graphing calculators is thrown on as a second function which makes it a pain when you are entering these massive numbers. The one major disadvantage of this TI-89 is you must use the 2nd function key to find SIN, COS, and TAN. ...
The parent equation is y= Acos(bx-c) +d where A= amplitude, b is the period, c is the horizontal shift and d is the vertical shift flipping over the x axis makes this a -cosine graph so y=2cos(3x) +1 becomes y= -cos(3x-2) +3 Upvote • 0 Downvote Add comment Still...
In degree mode, complex identities such as e^(iq) = cos(q) + i sin(q) are not generally true because the values for cos and sin are converted to radians, while those for e^( ) are not. For example, e^(i45) = cos(45) + i sin(45) is treated internally as e^(i45) = cos...
