То чувство, когда 8 лет учил , но без понятия, что такое present simple passive. надо предложения в пассивном залоге в present simple написать?

Сначала формулы . затем формулы двойного угла sin2α=2sinαcosα cos2α=cos²α-sin²α=cos²α-(1-cos²α)=2cos²α-1⇒  2cos²α=1+cos2α cos2α=cos²α-sin²α=1-sin²α-sin²α=1-2sin²α⇒  2sin²α=1-cos2α а) сos75°cos105°=cos(90°-15°)·cos(90°+15°)== sin15°(-sin15°)=-sin²15°=-(1-cos30°)/2=(cos30°-1)/2= ((√3/2)-1)/2=0,25√3-0,5б) sin75°sin15°=°sin(90°-15°)sin15°=cos15° sin15°=sin30°/2=1/4=0,25в) sin105°cos15°=sin(180°-75°)cos15°=sin75°cos15°=sin(90°-15°)cos15°=cos15°cos15°=(1+cos30°)/2=(1+(√3/2))/2=0,5 +0,25√3 2 способ формулы cosα·cosβ=0,5cos(α-β)+0,5cos(α+β) sinα·sinβ=0,5cos(α-β)-0,5cos(α+β) sinα·cosβ=0,5sin(α+β)+0,5sin(α-β) а) сos75°cos105°=0,5cos(75°-105°)+0,5cos(75°+105°)=0,5cos(-30°)+0,5 cos180°==0,5· √3/2+0,5·(-1)=0,25√3-0,5б) sin75°sin15°=0,5cos(75°-15°)-0,5cos(75°+15° )=0,5cos60°-0,5 cos90°=0,5·0,5=0,25в) sin105°cos15°=0,5sin(105°+15°)+0,5sin(105°-15°)= =0,5sin120°+0,5sin90°==0,5 sin(180°-60°)+0,5·1=0,5 sin 60°+0,5=0,25√3+0,5

I love everything alive - cute cats, dogs loyal, noble lion, sly foxes, squirrels charming, colorful fish, birds chirping, and many, many others. But most of all I love dolphins. These amazing mammals always cause tenderness and a smile on my face.

I visited with my parents often dolphins at sea, to look at these most intelligent beings with good and intelligent eyes, to look directly into the soul. And every trip to the dolphinarium was for me - like a real holiday. On this day, I always get up early in the morning and wanted only one thing, to quickly come campaign time.

Coming to the Dolphinarium, I immediately plunged into a real euphoria of universal excitement. After all, we can not wait to hurry to get to his place on the podium and watch the view. And the audience took their seats, and, finally, under the solemn music in the arena dolphinarium leave people in bathing suits - the coaches and trainers of dolphins. Their output of all the spectators greeted with thunderous applause.

And the very idea begins in just a few seconds, where dolphins, sea lions and fur seals perform all kinds of tricks on command of their trainers
