Trigonometry

Oh, dude, let me break it down for you. So, if you draw three lines in a circle, you can definitely create eight pieces. Each line you draw cuts the circle into two parts, so with three lines, you'll have eight pieces in total. It's like slicing a pizza, but with geometry.

Oh, dude, you want a math working model for class 11? That's like asking for a unicorn at a pet store! But hey, you could make a cool model showcasing different geometric shapes or maybe demonstrate a math concept using everyday objects. Just remember, it's all about having fun with it, not stressing out too much.

To find the multiplicative inverse of a complex number z = (a + bi), divide its complex conjugate z* = (a - bi) by z* multiplied by z (and simplify):

z = 4 + i

z* = 4 - i

multiplicative inverse of z:

z* / (z*z)

= (4 - i) / ((4 - i)(4 + i)

= (4 - i) / (16 + 1)

= (4- i) / 17

= 1/17 (4 - i)

Trig helps to measure distances between objects without anyone actually having to travel to all the points. It should be noted that trig is used "in cartography" (in the practice of map-making), or used "by a cartographer" (by a map maker).-

The immediate surroundings of any point on a curved path can be considered as part of a circle: the circle of curvature at that point. Then the tangent to the path at that point is a line that meets the path at only one point in that neighbourhood and which is perpendicular to the line joining the point to the centre of the circle or curvature.

The concept can be extended to straight segments of the path by assuming that the centre of curvature is at an infinite distance. In that case, the path and its tangent are the same line.

Angle -1560 degrees lies in the fourth quadrant, honey. Just imagine spinning around in circles like a drunken sailor - you'll end up facing the fourth quadrant eventually. So, in math terms, that negative angle is gonna be chilling in the fourth quadrant where negativity is welcome.

In the Cartesian plane, the independent variable, if any, is usually plotted on the x-axis.

Only when it is in the form of a right angle triangle that it will have perpendicular lines that meet at 90 degrees.

It is 0.

Let the angles be A B C and their opposite sides be a b c then by using the trigonometrical cosine rule the first two angles work out as 39.93 degrees and 88.05 degrees then deduct those angles from 180 degrees to find the third angle which will be 52.02 degrees.

Centre of circle: (3, -5)

Distance from (3, -5) to (6, -7) is the square root of 13 which is the radius
