## Did Bill Gates take Math 55?

Bill Gates took Math 55.

To get a sense of the kind of brains it takes to get through Math 55, consider that Bill Gates himself was a student in the course..

## Is trigonometry harder than calculus?

Calculus is harder than trigonometry. Because most of the trigonometry is used in calculus.

## What is the hardest math to learn?

## Do I have to memorize trig identities?

Many trig classes have you memorize these identities so you can be quizzed later (argh). You don’t need to memorize them, you can work out the formula in about a minute.

## How can I be good at trigonometry?

11 Tips to Conquer Trigonometry ProvingTip 2) Express everything into Sine and Cosine. To both sides of the equation, express all tan , cosec , sec and cot in terms of sin and cos . … Tip 4) Use Pythagorean Identities to transform between sin²x and cos²x. … Tip 7) Good Old Expand/ Factorize/ Simplify/ Cancelling.

## Why are proofs so hard?

Proofs are hard because you are not used to this level of rigor. It gets easier with experience. If you haven’t practiced serious problem solving much in your previous 10+ years of math class, then you’re starting in on a brand new skill which has not that much in common with what you did before.

## What does sin 2x equal?

1. sin(2x)=2sin(x)cos(x).

## What are the six trigonometric functions?

There are six main trigonometric functions:Sine (sin)Cosine (cos)Tangent (tan)Secant (sec)Cosecant (csc)Cotangent (cot)

## What is the hardest subject in the world?

Top Ten Hardest School Subjects Physics. For the majority of people, physics is very tough because it is applying numbers to concepts that can be very abstract. … Foreign Language. … Chemistry. … Math. … Calculus. … English. … Biology. … Trigonometry.More items…

## How do you solve hard trigonometric identities?

STEP 1: Convert all sec, csc, cot, and tan to sin and cos. Most of this can be done using the quotient and reciprocal identities. STEP 2: Check all the angles for sums and differences and use the appropriate identities to remove them. STEP 3: Check for angle multiples and remove them using the appropriate formulas.

## What math comes after calculus?

After completing Calculus I and II, you may continue to Calculus III, Linear Algebra, and Differential Equations. These three may be taken in any order that fits your schedule, but the listed order is most common.

## How do you prove trig identities?

For instance, sin(x) = 1/csc(x) is an identity. To “prove” an identity, you have to use logical steps to show that one side of the equation can be transformed into the other side of the equation. You do not plug values into the identity to “prove” anything.

## What is the point of Trig identities?

Trig identities are trigonometry equations that are always true, and they’re often used to solve trigonometry and geometry problems and understand various mathematical properties. Knowing key trig identities helps you remember and understand important mathematical principles and solve numerous math problems.

## Is Cos Sin Tan?

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x . … 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 the highest level of math?

CalculusBegin with Algebra 1 and Geometry, often considered the building blocks of higher level math and science classes. Wrap up with Calculus, the highest level of math offered by many high schools and often considered the gold standard of pre-college math preparation.
