How do you find the principal value?

We can rearrange the interest formula, I = PRT to calculate the principal amount. The new, rearranged formula would be P = I / (RT), which is principal amount equals interest divided by interest rate times the amount of time.

What is the principal value of cos?

Domain and Principal Value of Inverse Trigonometric Functions. We know that the principal value of the trigonometric function at a point is the value of the inverse function at a point , which falls in the range of principal values unit. The principal value of cos √(3/2) is π/6 as π/6 ∈ 0,π.

What is the principal value of tan 1?

π/4
So, the principal value of tan-1(1) = π/4.

What is principal value of logarithm?

The principal value of logz is the value obtained from equation (2) when n=0 and is denoted by Logz. Thus Logz=lnr+iΘ.

Is the principal value?

Principal Solution : The solution in which the absolute value of the angle is the least is called principal solution. For example the value of cos o° is 1, the value of cos 2π, 4π ,…… are also 1. But the 0 is known as principal value.

What is principal value of Sinx?

The principal value of sin−1 x for x > 0, is the length of the arc of a unit circle centred at the origin which subtends an angle at the centre whose sine is x. For this reason sin^-1 x is also denoted by arc sin x.

What is the principal value of Cos inverse COS 680?

Principal value of cos-1(cos680∘) will lie between 0 and 180∘. So, principal value of given expression is 40∘.

What is the principal value of Sinx?

The principal value of sin−1 x is α, where – π2 ≤ α ≤ π2 and α satisfies the equation sin θ = x.

What is the principal value of cot inverse minus root 3?

Hence, the principal value of cot-1(√3) is π/6.

What is the principal value of cot inverse?

The principal value of cot^(-1)(-1) is Let cos-1(-1)=x, where x∈[0,π].

What is the principal value of log (- 3?

Originally Answered: What is the general value of Log(-3)? = (1/2) ln(x^2 + y^2) + i arctan(y/x).

What is arg of z?

In mathematics (particularly in complex analysis), the argument of a complex number z, denoted arg(z), is the angle between the positive real axis and the line joining the origin and z, represented as a point in the complex plane, shown as. in Figure 1.
