counter clockwise would be rotating it up to the right.
C is 4 spaces away from A ,
A is on X3 & Y3 so 4 +3 = 7
so it would be x7 & Y3 so (7,3), the first answer
The answer is the one on the top
First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb
tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx,
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx,
</span> because <span>cospi/2 =0, </span>and <span>sinpi/2=1
</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>
Step-by-step explanation:
is this a quadrilateral? or polygon or triangle?
what are the angles (I believe there should be at least an angle given) else PC can be any value that is positive
Answer:
0
Step-by-step explanation:
For common denominator,
6/8 - 3/4 = 6/8 - (3*2)/(4*2) = 6/8 - 6/8 = 0
