Help me to solve this math trig

2sinx(1 + cos2x) + sin2x = 1 + cos2x-2sinx(1 + cos2x) + sin2x = 1 + cos2x 2sinx(1 + 2cos²x - 1 ) + 2sinxcosx = 1 + 2cos²x - 1 2sinx(2cos²x) + 2sinxcosx - 2cos²x = 0 4sinxcos²x + 2sinxcosx - 2cos²x

I need to find the "d" value in arithmetic sequence

I have: -7, -2, 3, 8 I know D= difference. And you need to do like: I want to find this term so thatd be my x (unknown) and then i would have these numbers what i know are right? Or something like th

What grade is Calculus II designed for (e.g. grade 10, 11, 12,)

There is no specific level that class is designed for.In most cases, 11th and 12th graders get to take Calculus II if they do very well in Pre-Calculus and/or other advanced math courses.It all depend

Reducing rational expression to lowest terms

Reduce the following rational expression to lowest terms, if possible. c^2-6c+9/c-3 i got c+2-3 but its not correct, can you please explain how to do this.-(c^2-6c+9) / (c-3) = (c-3)(c-3) / (c-3)//

ECE 300 Help! Need to transform equations using trigonometric identities, (AC curcuit analysis)

Transform the following equations into the form x(t) = Xmcos(wt+theta) using the sum and difference trigonometric formulas 1:v1(t) = 1.5 cos(2πt) − 0.75 sin(2πt) if someone could just help me get st

How did I pass my math class

Tests were worth 60, homework 10%, quizzes 10% and Final 20%. On my test my average was a 64 which is a 38.4.My homework was a 9.3 and my quizzes came out to a 9.2. My final was a 7.4. If you add them

Please help if you are good in geometry!!

im going to fail my takehome test and im already doing bad in this class! if anyone can help that would be so great! 5. Find the length of a side of the rhombus whose diagnals measure 12 and 16 7. In

Solve simultaneously x^x + y^x= 13 y^y - x^y = 19

2^2 + 3^2 = 13 3^3 - 2^3 = 19 x = 2, y =3 just trial and error :-)-by the looks of things, x cant be equal to y x and y must be > 1 ===> if x and x and y must be ===> if x > 4 and y > 1, then equal

Prove there are no constant polynomials in Zp[x] that have multiplicative inverses.

Let p be a prime.Are there any nonconstant polynomials in Zp[x], that have multiplicative inverses?Explain your answer. I know the answer is no, just curious how to get it.Thanks!-Let f(x) be a nonco

What is the cot 0 =

a. 0 b. -SquareRoot3/3 c. undefined d. 1-The tangent of 0 (tan0) is 0 (A). However, since the cotangent (cot) is the reciprocal of the tangent, we know that the equation used for cot is 1/tan. Therefo

What is the vertical asymptote(s) for y =(x-5)/(x^2-4x-12)

please help i dont know the vertical asymptote. thanks-Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. According with the statement, le

Which point lies on the unit circle? explain

a. (-35/37, 12/37) b. (16/53, 37/53) c. (119/74, -45/74) d. (-49/51, -2/51)-The answer is a) A unit circle is defined as a circle of radius 1 and its origin/centre at (0,0). as the radius is 1, the

How would i find the common denominator of this... 10th grade me

Whats the common denominator of these 3? (2/x-3) and (3/2x+3) (3x/x-2) and (2/x^2-4) the one that looks the hardest.... (x/3x(x+3) and (1/x^2-9) and (4/x(x-3) i have an idea of doing it, like what

What is the fifth term of (3x-4)^12

1. x=0 16777216 2. x=1 1 3. x=2 4096 4. x=3 244140625 5. x=4 68719476736 6. x=5 3138428376721 considering x=0 as the first term and x=4 as the fifth term
