Answer:
F(a)=2a^2+4a+5
Step-by-step explanation:
Put "a" where "x" is in the function definition:
F(a)=2a^2+4a+5
It goes in 5 times but with 1 remainder
Answer:
Step-by-step explanation:
sin(180°-∅)=sin∅ as its in the 2nd quadrant
then tan(180°-∅)= -tan∅ as its in the 2nd quadrant and there only sin and cosec is positive and at last cos(180°-∅) = -cos∅ for the same reason
so by putting the values:
sin∅/sin∅ + -tan∅/tan∅ + -cos∅/cos∅ =1-1-1= -1
