Calculus

Regardless of what 'x' is, (x)0 = 1 .

tan(1 radian) = 1.55741 (rounded)

tan(1 degree) = 0.01745 (rounded)

We can't remember the derivative of the tangent right now, but it doesn't matter.

This particular tangent is a constant, so its derivative is zero.

Impossible to give a correct solution in the absence of any plus or minus signs.

One millionth (1/1000000) of kL makes 1 mL

1 kL = 1000 L = 1000000 ml

Hyperbolic functions can be used to describe the position that heavy cable assumes when strung between two supports.

x = 0

5x + 7 = 3x - 5

Subtract 3x from both sides: 2x + 7 = -5

Subtract 7 from both sides: 2x = -12

Divide both sides by 2: x = -6

The amplitude is ' 1 ' .

36/1, 72/2, .36*10^2, 36*1, 18*2, 6*6

for the equation:
5x + 10y = 20, the two intercepts are:
x = 0 , y = 2 or (0,2)
y = 0 , x = 4 or (4,0)

The graph is a straight line passing through the two intercepts (0,2) and (4,0)

In most situations, the answer that is looked for is linear.

However, since y=mx+b does not follow superposition, it is in fact, nonlinear.

Proof:

y1=mx1+b

y2=mx2+b

x3=Ax1+Bx2

y3=m(Ax1+Bx2)+b=mAx1+mAx2+b

this does not equal Ay1+By2, making it nonlinear

Well, honey, to solve for X when X + Y = 22, you just need to subtract Y from both sides of the equation. So, X = 22 - Y. There you go, math problem solved quicker than you can say "Golden Girls marathon."

x=1, y=1 looks a good guess which turns out to be correct. Add on half of the first equation to itself (so we get another "3x" equation) to get -3x-15y=-18. Now add the 2 equations to get rid of the 3x, giving you -9y=-9 or y=1. Use y=1 in either equation to get x=1.

In general you can turn one equation around to give x in terms of everything else. The substitute your expression for x into the other equation which will give you an simple equation for y only.

The method I used above found an expression for 3x rather than x alone because that's easier to substitute into the other equation.

if you mean x +13/3=7, then its 8/3. However, if you mean x+41.3=7, then x=-34.3

y=x/4

No because the discriminant is less than zero.

The base 10 logarithm is called the "common logarithm".

It is also called the 'Briggsian logarithm', named after Henry Briggs, who introduced his table of logarithms on base 10 at Oxford in 1624, much to the joy of navigators, astronomers, and others having tedious calculations to perform.

2x +1 = 5x-2

2x +3= 5x

3 = 3x

x=1

1:8.4

5.34 x 9.4 = 50.19600

To isolate the "x", you divide both sides (left and right of the equal sign) by 25.

To isolate the "x", you divide both sides (left and right of the equal sign) by 25.

To isolate the "x", you divide both sides (left and right of the equal sign) by 25.

To isolate the "x", you divide both sides (left and right of the equal sign) by 25.

yes and the answr is x = 9

x+4y = 1

2x-2y = -8

Mutiply all terms in the bottom equation by 2 and then add them both together:

5x = -15

x = -3

Substitute the value of x into the equations to find the value of y:

So: x = -3 and y = 1

It is 2152500.

X and Y could equal any number of things.

For instance, if x=6 and y=0, then that will equal 24.

Or if x=8 and y=2, then that will equal 24.
