It's not. Cos(Θ) only gives you the x-component of a vector.
In order to find its y-component, you also need to use sin(Θ).
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
Theta is the classical Greek letter. It looks like an 'O', with an horizontal line through it. It is used as an angular symbol in Trigonometry. e.g. Sin (Theta) = 0.5 So inverting Theta = 30 degrees.
If tan theta equals 2, then the sides of the triangle could be -2, -1, and square root of 5 (I used the Pythagorean Theorem to get this). From this, sec theta is negative square root of 5. It is negative because theta is in the third quadrant, where cosine, secant, sine, and cosecant are all negative.
Well, darling, the Greek letter used to represent an angle is "theta." It's like the Beyoncé of the Greek alphabet, strutting its stuff in geometry and trigonometry like nobody's business. So, next time you see that symbol, just remember it's here to slay those angles.

The cosine function is used to determine the x component of the vector. The sine function is used to determine the y component. Consider a vector drawn on an x-y plane with its initial point at (0,0). If L is the magnitude of the vector and theta is the angle from the positive x axis to the vector, then the x component of the vector is L * cos(theta) and the y component is L * sin(theta).
You usually need all three primary functions. The sine and cosine functions are used to resolve the vector along orthogonal axes, and the tangent function is used to find its direction.
Front functions such as vector::front(), list::front() and queue::front() return the first object in a container class. Not to be confused with begin() functions such as vector::begin() which return an iterator object which is typically used in iterative functions (loops) to traverse the objects within a container.
The complex number exp(i theta) is significant in trigonometry and exponential functions because it represents a point on the unit circle in the complex plane. This number can be used to express trigonometric functions and rotations in a concise and elegant way, making it a powerful tool in mathematical analysis and problem-solving.
When a point ((x, y)) is rotated around the origin by an angle (\theta), the new coordinates ((x', y')) can be determined using the rotation formulas: (x' = x \cos(\theta) - y \sin(\theta)) and (y' = x \sin(\theta) + y \cos(\theta)). This transformation effectively changes the point's position in a circular motion around the origin based on the specified angle. The direction of rotation (clockwise or counterclockwise) also affects the signs of the trigonometric functions used.
A theta is the latin word for a specific symbol used in mathematical equations. The theta means the angle. You use the theta symbol to say "angle". The symbol is useful when you don't know the degree of the angle is. * * * * * Theta is not Latin nor is it a word. It is a letter of the Greek alphabet. It is used to stand for an unknown angle in the same way that the Roman letters x or y are used in algebra.
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
Vector curves are mathematical representations of curves in a vector space, often used in computer graphics to define smooth shapes and paths. They are defined by a series of control points and mathematical functions that interpolate between these points to create a smooth curve. Vector curves are widely used in design software like Adobe Illustrator and Inkscape for creating precise and scalable shapes.
When used to indicate angles, "theta" is an unknown (exactly like using "x" for the unknown in equations).
In trigonometry, theta is a symbol commonly used to represent an unknown angle in the same way you might use x to label an unknown side or an unknown number in general. Theta looks like this: θ
'Theta' is a zero-looking Greek letter with a line across. It is used in physics and many mathematic equasions.
A positive selection vector is a type of vector used in molecular biology that contains a gene conferring a specific trait or resistance to a selection agent, such as an antibiotic. This allows for the selection of only those cells that have successfully taken up the vector and integrated the gene.
