1. Is there a way to simplify finding the minimum distance between two objects approach?

The problem is as follows: Two buggies one orange and the other blue are passing through an intersection with constants speeds of $v_{orange}=6\,\frac{m}{s}$ and $v_{blue}=6\sqrt{3}\,\frac{m}{s}$ respectively. Find the minimum approach in meters between the orange and blue buggies. The...
2. How to simplify this expression involving a tangent of 70?

My situation is as follows. Can the expression from below be simplified using precalculus and plain by hand calculation without requiring a calculator? $$B=\sqrt{3} \tan 70^{\circ}- 4 \sin 70^{\circ}+1$$ What I attempted to do was to split the functions in a sum of $30^{\circ}+40^{\circ}$...
3. How to simplify a sum of multiples of secants?

I've got tangled into this problem, so I hope somebody could help me. The problem is as follows: Find the value of $\textrm{H}$ which belongs to a certain vibration coming from a magnet. $$H=\sec \frac{2\pi}{7}+\sec \frac{4\pi}{7}+\sec \frac{6\pi}{7}$$ It was easy to spot that each term was...

5. Simplify modulus expression

Can someone tell me how to simplify this expression with modulus: (A/100) mod 10 + (A/10) mod 10 + A mod 10 where A is an integer, but it can also be not divisible by 100. I tried doing this, but it doesn't work... (A/100+A/10+A)mod 10 Thanks

7. what is: sin(a+b)/sin(a-b)

is there any simpler way to write this, I already looked at all the trigonometric identities, I couldn't find anything about fractions of sums. I also try to find: cos(a-b)+cos(a+b) how do I do this, is there anything I'm missing?

16. Can you simplify this equation?

L/((1-1/((1+r)^a))*(1-1/((1+r)^b))) or L ________________________________ (1 - 1/((1+r)^a)) * (1 - 1/((1+r)^b)) or is this as simple as it gets :)
17. Trigonometrical Equation, don't know how to simplify it

Hi everyone. I have an expression -cos(f)*(sin(g)*cos(m)*cos(l) + sin(g)*sin(m)*sin(l)) + cos(g)*sin(f) which is equal to cos(g)*sin(f) - cos(f)*sin(g)*cos(l - m) according to Wolfram Alpha's CAS. I have no clue how to get there. :eek: Thanks in advance, Peter
