How do you find the sum and difference of tangent?
Space and AstronomyWhat is the difference formula for tangent? To determine the difference identity for tangent, use the fact that tan(−β) = −tanβ. Example 1: Find the exact value of tan 75°. Example 2: Verify that tan (180° − x) = −tan x. What is the sum and difference formula? Key Equations Sum Formula for Cosine cos(α+β)=cosαcosβ−sinαsinβ

Can the outer planets support life?
Space and AstronomyThe orbit must lie in the “habitable zone” where the exoplanet’s surface is just the right temperature for liquid water to exist. Every form of life we know requires liquid water, so an exoplanet too close or too far from its host star is less likely to contain life. Which planets could support life? Meet

When can you see the Moonbow?
Space and AstronomyThe moonbow typically appears for about five nights each month, starting from two to three nights before the full moon through two or three nights afterward – but only when the weather is clear. If it’s cloudy, there won’t be enough light. How rare is it to see a moonbow? Lunar rainbows — moonbows —

Why do we use functions in math?
Space and AstronomyBecause we continually make theories about dependencies between quantities in nature and society, functions are important tools in the construction of mathematical models. In school mathematics, functions usually have numerical inputs and outputs and are often defined by an algebraic expression. What are functions in math used for? Mathematical Functions A mathematical function is a

Can you find area with perimeter?
Space and AstronomyWhat is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area. Can you find area with just perimeter? You can calculate the area of a square by using both the length of one side and its perimeter. Divide the perimeter
