In radians:
To get 0, only one part of the multiplication needs to be zero for the whole thing to be zero. Thus we get 2 equations:
t=0, and cos(t)=0
for the first equation, it's pretty self-explanatory and sp we get 0 as one solution.
For the second equation, cos(pi/2) and cos(3pi/2) both equal 0 so both pi/2 and 3pi/2 are answers. Since there is no bound to this problem, the actual answer is:
(2Z+1)pi/2 and 0
(2Z+1) means all odd integers
Answer:
20
Step-by-step explanation:
(90+70)-(80+60)=20
just minus the total selling price to the total cost price
Answer:
n term=a+(n-1)r
Step-by-step explanation:
l do not understand question clearly.
You just add up all of the sides to find the x
180 - 16 - 63 = 101. The remaining angle is 101*
