Answer Verified 386.4k+views Hint:Express ${{270}^{\circ }}\text{ into }\left( {{270}^{\circ }}+\theta \right)$ . Then we should use the following two identities for sin and cosine respectively, $\sin \left( {{270}^{\circ }}+\theta \right)=-\cos \theta \text{...
Hint: In this question, we are asked to find out the sum of all positive integral divisors of a given number. As the positive integral divisors would be the numbers which are products of one or more factors of the given number, we should first find out the factors of ...
A Lagrange point is a region of space where gravitational and centripetal forces balance so that an object, such as a spacecraft or anasteroid, can remain stationary relative to a larger body, such as Earth. The Lagrange points are particularly useful for parking space probes. Does Earth have...
The designation μ0(pronounced asmu naughtormu zero) refers to the permeability of free space. It is also known as thepermeability of vacuumand themagnetic constant. InSI units, μ0was earlier equal to 4π × 10-7weber per ampere-meter. But with the redefinition of theamperein 2019, μ...
(sigma). generally, it is used when we have to add an extensive list or a sequence of numbers. sum of digits let’s understand how to find the sum of one-digit numbers, two-digit numbers, three-digit numbers, etc., with detailed explanations here. sum of one-digit numbers we can ...
What does 12! means in math? What is pre-calculus? Let S be the hemisphere z more than or equal to 0, x^{2} + y^{2} + z^{2} = 1 oriented upward. \vec{F} = (x, y, x^{2} + y^{2}). Find \int \int_{S}curl\vec{F}\cdot d\vec{S} ...
STEMinism is a portmanteau that combines the acronym STEM (science, technology, engineering and math) with feminism. STEMinists believe women should have equal opportunities and representation in theSTEMfields, which are typically male-dominated. STEMinists are individuals who support the STEMinism ...
a摇盖牢固,经开、合180度往复5次,实验外层和里层无裂缝。 Swings covers reliably, after opens, is equal to 180 degrees to move back and forth 5 times, the experimental outer layer and in the level does not have the crack.[translate]
\(\begin{array}{l}\sigma =\frac{f}{a}\end{array} \) where, σ is the compressive stress f is the compressive force a is the unit area dimension: its dimensional formula is [ml -1 t -2 ] . what is compressive strength? compressive strength is defined as the maximum compressive ...
Similarly, the cosine is defined as it is the trigonometric function which is equal to ratio of the length of the adjacent side to the length of the hypotenuse. There are six basic trigonometric ratios for the right-angled triangle. They are sin, cos, tan, cosec, sec, cot which stand...
