The speaker evidently feels that her daughter is growing up very fast and uncontrollably, through the lack of punctuation, caesura, and the almost continue use of enjambment throughout the poem. This lack...

Blood is primarily used to transport cells and different substances around the body. It can be divided into 4 categories of components: the blood plasma, trombocytes (platelets), leukocutes (white blood c...

One helpful method for solving questions like these is to sketch the curve in stages. First begin with the straight line y=3x+4 (taking 3x+4 from within the modulus lines) crossing the x axis at -4/3 and ...

sin(A+B) ≡ sin(A)cos(B) + sin(B)cos(A)

⇒ sin(75°) = sin(30+45)° = sin(30°)cos(45°) + sin(45°)cos(30°)

= ½ × 1/√2 + 1/√2 ×(√3)/2 = 1/(2√2) + (√3)/(2√2)

= (1+√3)/(2√2)
