Now, we will use the concept of circle and find the value of $cos 8pi $.Complete step by step answer:We have to find the exact value of $cos 8pi $.Now, we know that the sum of the central angle of a circle is equal to $360{}^circ $. It means if we go once around the circle we go through an angle $2pi $. Now, we know that cosine is the circular function so we will get $cos 2pi =1$ Now, if we go the second time through the circle we get the angle as $4pi $.Similarly if we go third time through the circle we get the angle as $6pi $.Finally if we go through the circle fourth time we get the angle as $8pi $.But after the four revolutions we are at the same point where we started so the value of cosine function remains the same.So we will get $cos 8pi =1$.Note: Pi was first described as the quantity which, when multiplied by diameter of the circle gives the circumf…MoreSarthaks eConnectQuestionThe number of solutions of the equation cos2(π3cosx−8π3)=1cos2(π3cosx-8π3)=1 in the interval [0,10π][0,10π] isAnswer · 0 votesCorrect Answer - Ccos2(π3cos.X−8π3)=1cos2(π3cos.X-8π3)=1⇒π3cos.X−8π3=kπ,(k∈Z)⇒π3cos.X-8π3=kπ,(k∈Z)⇒cosx=3k+8,k∈Z⇒cosx=3k+8,k∈Z⇒cosx=−1⇒cosx=-1, when k=−3k=-3⇒⇒ there are 5 solutions for x∈[0,10π]x∈[0,10π]MoreStack ExchangeQuestionI believe this to equal 6π/7 using a reference angle of π/7, is this thinking correct or do the inverse of cos and cos just cancel out?
