Why is CSC the inverse of sin?
We know that the cosecant is the reciprocal of the sine. Since sine is the ratio of the opposite to the hypotenuse, cosecant is the ratio of the hypotenuse to the opposite.
Is CSC and sin 1 the same?
It is important to note that there is a big difference between the reciprocal value csc θ and sin-1x. The cosecant function means 1/sin θ, while the second involves finding an angle whose sine is x.
What fraction is cosecant?
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
What is sec1 math?
Secondary 1 Mathematics Course Overview More crucially, they will be taught important skills and concepts in Algebra as they learn how to manipulate algebraic expressions, use algebra (instead of model-drawing) to solve challenging word problems and sketch graphs of linear functions to solve linear equations.
What is derivative of Cscx?
The derivative of cosec x is negative of the product of trigonometric functions cosec x and cot x, that is, -cosec x cot x. The differentiation of csc x is the process of evaluating the derivative of cosec x with respect to angle x.
What trigonometric ratio refers to the adjacent side divided by the opposite side?
Finally, the ratio of the opposite side to the adjacent side is called the tangent and given the symbol tan. tan = o / a.
How do you find the opposite side of a hypotenuse and angle?
If you have the hypotenuse, multiply it by sin(θ) to get the length of the side opposite to the angle. Alternatively, multiply the hypotenuse by cos(θ) to get the side adjacent to the angle.
Who invented sine?
Sine was introduced by Abu’l Wafa in 8th century, as a more convenient function, and gradually spread first in the Muslim world, and then to the West. (But apparently it was used in India centuries before him), as a more convenient function. However this new notation was adopted very slowly, it took centuries.
What is arcsecant?
arcsecant – the inverse function of the secant; the angle that has a secant equal to a given number.
What is an arc secant?
Definition of arc secant : the inverse function to the secant if y is the secant of θ, then θ is the arc secant of y — called also inverse secant
Why are there no answers in philosophy?
In Philosophy it’s not that there are no answers it’s just that the answers are very difficult to find. Peter Worley speaking at the Battle of Ideas 2015 ‘ Can Children Do Philosophy?
Is philosophy something other than what we say it is?
So, consistent with the philosophical spirit we’ve tried to illustrate here, one might wonder whether philosophy is – at least in addition to what we have said it is – something other than what we have said it is; to accept our account uncritically would not be very philosophical, after all.
