WebHow do you find the vector angle with the x-axis? For a vector that is represented by the coordinates (x, y), the angle theta between the vector and the x-axis can be found using the following formula: θ = arctan(y/x). What is a vector angle? A vector angle is the angle between two vectors in a plane. Webcosecant, secant, and cotangent are basically flipping the fractions which is called reciprocal. E.g: 3/5 is turned into 5/3 when reciprocated. cos-1, sin-1, and tan-1 are when you use the same fractions but reverse their purpose. E.g: you use cos (55°) to find the side length and in another case you use cos-1(2/4) to find a missing angle. Web$\begingroup$ "How would you calculate" is not clear enough. You did post a diagram, which is helpful. But you did not indicate what is known about the triangle. Is it the three sides?

How would one calculate the cosine of an obtuse angle?

WebAs can be seen from the figure, cosine has a value of 0 at 90° and a value of 1 at 0°. Sine follows the opposite pattern; this is because sine and cosine are cofunctions (described … WebTo find the area of the region, we need to integrate the difference of the two curves with respect to x: A = ∫ (pi/4 (2 - x) - arccos (x/2)) dx from x = 0 to x = 2. We can evaluate this integral using integration by substitution: Let u = x/2, then du/dx = 1/2. dx = 2 du. Substituting, we get:
