    Radians Tangent
AI Thread Summary
To solve the equation tan(theta) = 2/5, the arctangent function is used, which gives the angle in radians. The solution provided, 2.62 radians, is likely derived from calculating arctan(2/5). It's important to ensure the calculator is set to the correct mode, either degrees or radians, depending on the desired output. If using a calculator, inputting arctan(2/5) will yield the angle, but it may need to be adjusted based on the mode. Understanding these steps is crucial for solving trigonometric equations effectively.

The Attempt at a Solution


I forgot how, I had no clue so I looked in the solutions and it was 2.62 radians, I just don't know how they got that, I am not sure on what to do. Its for trigonometric forms of complex numbers.


Thanks for any help!

You don't have a calculator or something?
Usually that's the way to solve a problem like this, unless you want to iterate it...
 
Whats do i type in? A friend told me to do the arctan of 2/5 but that just gives me some decimal.
 
Is your calculator in DEG? if not, then put it in RAD
 

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Greatest possible value of a constant in polynomial'

Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
