Sin and cos functions can never be equal to 5. They can never be greater than 1! Both!
You can think of sin and cos functions as projections (that is how i do). Imagine xy coordinate system. Draw a circle which center (center of circle) is in center of xy coordinate system. Let radius of that circle be one (you can take one to be any length you want).
Now, x - axis and any radius of that circle make an angle.
NOW HERE IS IMPORTANT PART:
-projection of that radius on x-axis is cosine of the angle that radius and x-axis make.
-projection of that radius on y-axis is sinus of the angle that radius and x-axis make.
From that you can see that projections cannot ever be greater than 1.
Answer:
a)4
Step-by-step explanation:
(a+b)²=43 eqn 1
(a²+b²)=35 eqn 2
solving eqn 2 by putting the value of (a+b)² by eqn 1
- (a+b)²-2ab=35
- 43-2ab=35
- -2ab=35-43
- ab= -8/-2
- ab =4

Answer:
x=-2
Step-by-step explanation:
6(x + 1) = -2(3x + 9)
Distribute 6 and -2.
6x+6=-6x-18
Move the variable to the left-hand side and move the constant to the right and change their signs.
6x+6x=-18-6
Collect like terms.
12x=-24
Divide both sides of the equation by 12.
x=-2
Hope this helps :)
Answer:
The answer is 1…
Step-by-step explanation:
Well you can elimate a lot of fractions right off the bat just multiply everything by 60/1.
the final result will be
(240+15+40)+ (300+90-72)- (360+105+24)
Now solve
240-15+40=265
300+90-72=318
360+105+24=513
265+268-489
265+268= 11
533-513=20
bleh i m not sure naymore
