Trigonometry

Physicists use trigonometry whenever two or more vectors (fields, forces, momentums, etc...) interact with one another. Trigonometry is especially useful in modeling waves an, which transfer energy in a manner consistant with trigonometric functions. The same is true with oscillatory motion (like a spring bouncing up and down) and electrical current, which often varies in its strength like a spring bouncing (this is AC current).

The absolute value of something is also the square root of the square of that something. This can be used to solve equations involving absolute values.

Advantages of secant method:

1. It converges at faster than a linear rate, so that it is more rapidly

convergent than the bisection method.

2. It does not require use of the derivative of the

function, something that is not available in a number

of applications.

3. It requires only one function evaluation per iteration,

as compared with Newton's method which requires

two.

Disadvantages of secant method:

1. It may not converge.

2. There is no guaranteed error bound for the computed

iterates.

3. It is likely to have difficulty if f 0(α) = 0. This

means the x-axis is tangent to the graph of y = f (x)

at x = α.

4. Newton's method generalizes more easily to new

methods for solving simultaneous systems of nonlinear

equations.

this is nothing but its a noun

sin(x) = cos(90° - x)

cos(x) = sin(90° - x)

The side adjacent to theta divided by the hypotenuse, or the angle opposite of the right angle

It can have any value x degrees where 0 < x < 45.

sin(0)=0 and sin(very large number) is approximately equal to that same very large number.

Your question is CscΘ=? when SinΘ=2/3 in Q1

well bases on the fundamental identities.. Sin Θ= 1/CscΘ and CscΘ= 1/SinΘ

So when your in is 2/3

CscΘ=1/sinΘ

CscΘ =1/(2/3)

CscΘ = 3/2 -The value of cscΘ and it is positive because all functions in quadrant 1 are positive..

If you have more questions, please comment..:))

There are no universal rules. However, there are a number of situations : quadratic functions and their square roots for which trigonometric substitutions are effective.

At the origin.

Sine die means "indefinitely."

The answer depends on the nature of the problem.

You are referring to a special case of shape

its called a line

It is 1/4.

who invented subtraction?

Only one, they are all 90 degree angles.
