Corrections to my previous answers:
--------------------------------------------
for angle x between 180 and 270, cosine x = minus cosine (270 - x)

should have been

for angle x between 180 and 270, cosine x = minus cosine (x - 180)

and

for angle x between 180 and 270, sine (x) = minus cosine (270 - x)

should have been

for angle x between 180 and 270, sine (x) = minus sine (x - 180)

and I should have written

for angle x between 270 and 360, sine (x) = minus sine (360 - x)

and

for angle x between 180 and 270, tangent (x) = plus tangent (270 - x)

should have been

for angle x between 180 and 270, tangent (x) = plus tangent (x - 180)

Again, it is best to look in a text book, e.g.,
see 'Algebra and Trigonometry' (Second edition) by Stanley I. Grossman
page 426 of Chapter 7 on reference angles.

[input]23--5/49+-7[/input]
23--5/49+-7 = 16.10204081632653

This is a calculator website... why not put the problem through the calculator instead of the forum?

Ok lets break this problem into 3 easy parts and combine the like terms:
2ab-8ab,
-7cd+3cd,
and -6ef-4ef.
1. Solve 2ab-8ab, which is -6ab.
2. Solve -7cd+3cd, which is -4cd.
3. Solve -6ef-4ef, which is -10ef.
4. Now combine the 3 problems into 1 problem again, which would be -6ab-4cd-10ef

2ab-8ab-7cd+3cd-6ef-4ef = -6ab-4cd-10ef

{Math Check}
(The letters are left out in the imputs, because the imputs won't work correctly with the letters included, but for all practical purposes the math will still be true.)

Mighty Ryan:
the whole number portion is the product of all prime numbers between 4 and 10

primes: 5, 7

whole number = 5*7=35
tenthdigit = 1/4*lcm( 6, lcm(12, 8) ) = 6
hundredthsdigit = 1/2 * 6 = 3
thousandthsdigit = 7

Also, the note where it says I had already multiplied the numbers by 10, is wrong. I meant to delete that line, but forgot. I did not multiply those numbers by 10. Also, thank you admin for explaining that question!

you kids now a days are ridiculous.... no one is gonna help you hopefully....

GuestNov 13, 2012

x^2*y*(xy)^3 <-- I am assuming that is what you meant. ==x^5 * y^4 is the simplified form. First expand the cubed(^3) into the brackets then multiple the x and x together and the y's together as well. When you multiply like terms with exponents you need to add the exponents.

(150 meteres / 5 seconds) *(1 s/1000 ms)== (150m *1s)/(5 seconds*1000ms)== m/ms

-_- what are we even solving?

All right. I wish that this was accomplished at once, if it possible.
