cosθ 1 0 −1 0 1 Notice the pattern θ 0 π6 π4 π3 π2 cosθ 42 32 22 12 02 Explore by rotating the hypotenuse about the circle's center. By calculating the ratio adjacent/hypotenuse for different values ofθ, we can construct the graph ofcosθ. Change the value of r with...
We know that thesecant functionis the ratio of the hypotenuse and the adjacent side in a right-angled triangle. It can also be written as the reciprocal of the cosine function. Therefore the domain of sec x does not contain values where cos x is equal to zero. We know that cos x is ...

In summers, the duration of daylight is greater as compared to the duration of daylight in winters. There is a natural illumination in the environment at the day time, on the other hand there is darkness at the night time.Answe...
2. 节点的度数导致数值在图中不对称缩放：简单地说，具有较多邻居(较高度)的节点将以邻居聚合的形式从...
r=5+5cosθ Graphs: The graph of the polar equation of the cartesian equation in the two-dimensional system is found using the plotting the points methods. We find the value of the function along the different value of the variable. ...
Origin supports free rotation of OpenGL graphs by simply holding down the R key and using the mouse. Additional options for rotating, resizing, stretching and skewing are available when the 3D graph layer is selected. The graph can be created from an online template, 3D Surface Map Multiple ...
