Trigonometry

Suppose, Z is a function of X and Y. In case of Partial Differentiation of Z with respect to X, all other variables, except X are treated as constants. But, total derivative pf z is given by,

dz=(partial derivative of z w.r.t x)dx + (partial derivative of z w.r.t y)dy

By itself, sin theta has no use at all. Similarly, there is no use for the number 14. It is only in the context of something, or things, that measure that value is there any sue for it.

The area of a triangle is one half base times height.

1/2 b h = 120

1/2 130 h = 120

65 h = 120

h = 120/65

h = 1.85

It is: 75/3 = 25

You need to know the value of x

It simply reduces to the pythagorean theorem

Converting radian into degree:

5π/12 radian = {(5π x 180)/(12 x π)}o = 75o

So, cos(5Ï€/12) is equivalent to cos75o and cos 75o = 0.92175126972.

It is 0.8746

cos A=3/5

sin=square root of (1-cos2)

sin=square root of (1-3/52)

sin=square root of (1-9/25)

sin=square root of (16/25)

sin=4/5

csc=1/sin

csc=1/(4/5)

csc=5/4

Yes.

In geometry, a heptagon is a polygon with seven sides and seven angles.

65 square meters times 0.01 meters (one centimeter) equals 0.65 cubic meters.

It is (5*pi/6)*8 = 20*pi/3 m.

Refer to Euclid

I will assume that this is a right triangle and neither side length is the hypotenuse.

In the case that this is a right triangle and neither side length given is for the hypotenuse, you would use tangent to solve for your angle measure.

tan(Q) = the length of the side opposite of Q/the length of the side adjacent to Q.

So for this answer:

**NOTE: Side a is traditionally the side opposite to angle A.**

tan(A) = a/b *where b is not the hypotenuse

=>

tan(A) = 76.4/39.3

tan(A) = 1.94402...

A = arctan(1.94402...) *arctan is the same thing as inverse tangent or tan^(-1)

A ~= 62.78 Degrees * ~= means approximately.

***Extra stuff:

tan = opposite/adjacent

sin = opposite/hypotenuse

cos = adjacent/hypotenuse

The sine of 20° is approximately 0.342.

yes

Fraction!

5 parts-- pentagon

6 parts-- hexagon

Eta precedes theta.

Cosine to the negative first power and cosine cancel each other out because cosine to the negative first power is one over cosine, and one over anything times anything is just one.

To Deduce?

Step I: Show that both points are outside the smaller circles. Possibly by showing that distance from each point to the centre of the circle is greater than its radius.

Step 2: Show that the line between the two points touches the circle at exactly one point. This would be by simultaneous solution of the equations of the line and the circle.

One important qualification is to be able to communicate well and to do that you need to be able to spell correctly.

1 meter is 3.28 feet. For instance, if your elevation is 60.38 meters, it means that it is 60.38 by 3.28 = 198.10 feet
