高中数学 课时跟踪训练1 任意角 新人教A版必修4-新人教A版高一必修4数学试题

课时跟踪训练(一)(时间45分钟) 题型对点练(时间20分钟)题组一 任意角的概念 1.给出下列说法: ①锐角都是第一象限角; ②第一象限角一定不是负角; ③第二象限角是钝角;④小于180°的角是钝角、直角或锐角.其中正确命题的序号为________(把正确命题的序号都写上).[解析]①正确;②错,若顺时针旋转终边落在第一象限,则为负角;③错,第二象限角不都是钝角,钝角都是第二象限角;④错,小于180°的角包括负角和零角.[答案]①2.将时钟拨快20分钟,则分针转过的度数是________.[解析] 时钟拨快20分钟,相当于转了13小时.因为时针转过1小时,分针转-360°,所以时针转13小时,分针转过的度数为13×(-360°)=-120°.[答案] -120°3.写出图(1),(2)中的角α,β,γ的度数.[解] 题干图(1)中,α=360°-30°=330°; 题干图(2)中,β=-360°+60°+150°=-150°;γ=360°+60°+(-β)=360°+60°+150°=570°.题组二 终边相同的角与象限角4.与405°角终边相同的角是( )A .k ·360°-45°,k ∈ZB .k ·180°-45°,k ∈ZC .k ·360°+45°,k ∈ZD .k ·180°+45°,k ∈Z[解析] 因为405°=360°+45°,所以与405°终边相同的角为k ·360°+45°,k ∈Z .[答案] C5.-435°角的终边所在的象限是( ) A .第一象限 B .第二象限 C .第三象限D .第四象限[解析] 因为-435°=-360°-75°,而-75°为第四象限角,所以-435°为第四象限角.[答案] D6.若角α,β的终边相同,则α-β的终边在( ) A .x 轴的非负半轴 B .y 轴的非负半轴 C .x 轴的非正半轴D .y 轴的非正半轴[解析]∵角α,β终边相同,∴α=k ·360°+β(k ∈Z ),∴α-β=k ·360°(k ∈Z ),故α-β的终边在x 轴的非负半轴上.[答案] A题组三 角αn,(n ∈N *)所在象限的确定7.已知α为第一象限角,则α2所在的象限是( )A .第一象限或第二象限B .第一象限或第三象限C .第二象限或第四象限D .第二象限或第三象限[解析] 由于k ·360°<α<k ·360°+90°,k ∈Z , 得k ·180°<α2<k ·180°+45°,当k 为偶数时,α2为第一象限角;当k 为奇数时,α2为第三象限角.[答案] B8.已知角2α的终边在x 轴的上方,那么α是( ) A .第一象限角 B .第一、二象限角 C .第一、三象限角D .第一、四角限角[解析] 由题意知k ·360°<2α<180°+k ·360°(k ∈Z ),故k ·180°<α<90°+k ·180°(k ∈Z ),按照k 的奇偶性进行讨论.当k =2n (n ∈Z )时,n ·360°<α<90°+n ·360°(n ∈Z ),∴α在第一象限;当k =2n +1(n ∈Z )时,180°+n ·360°<α<270°+n ·360°(n ∈Z ),∴α在第三象限.故α在第一或第三象限.[答案] C综合提升练(时间25分钟)一、选择题1.给出下列四个命题:①-75°角是第四象限角;②225°角是第三象限角;③475°角是第二象限角;④-315°角是第一象限角,其中真命题有( )A .1个B .2个C .3个D .4个[解析]①正确;②正确;③中475°=360°+115°,因为115°为第二象限角,所以475°也为第二象限角,正确;④中-315°=-360°+45°,因为45°为第一象限角,所以-315°也为第一象限角,正确.[答案] D2.终边在直线y =-x 上的所有角的集合是( ) A .{α|α=k ·360°+135°,k ∈Z } B .{α|α=k ·360°-45°,k ∈Z } C .{α|α=k ·180°+225°,k ∈Z } D .{α|α=k ·180°-45°,k ∈Z }[解析] 因为直线y =-x 为二、四象限角平分线,所以角终边落到第四象限可表示为k ·360°-45°=2k ·180°-45°,k ∈Z ;终边落到第二象限可表示为k ·360°-180°-45°=(2k -1)·180°-45°,k ∈Z ,综上可得终边在直线y =-x 上的所有角的集合为{α|α=k ·180°-45°,k ∈Z }.[答案] D3.若φ是第二象限角,那么φ2和90°-φ都不是( )A .第一象限角B .第二象限角C .第三象限角D .第四象限角[解析]∵φ是第二象限角,∴k ·360°+90°<φ<k ·360°+180°,k ∈Z , ∴k ·180°+45°<φ2<k ·180°+90°,k ∈Z ,∴φ2是第一或第三象限角,而-φ是第三象限角, ∴90°-φ是第四象限角,故选B. [答案] B 二、填空题4.与角-1560°终边相同的角的集合中,最小正角是________,最大负角是________. [解析] 由于-1560°÷360°=-4×360°-120° 即最大负角为-120°,最小正角为240°. [答案] 240° -120°5.若α,β两角的终边互为反向延长线,且α=-120°,则β=________. [解析] 由题意知,β角的终边与60°角终边相同,则β=k ·360°+60°,k ∈Z . [答案]k ·360°+60°,k ∈Z 三、解答题6.已知α,β都是锐角,且α+β的终边与-280°角的终边相同,α-β的终边与670°角的终边相同,求角α,β的大小.[解] 由题意可知,α+β=-280°+k ·360°,k ∈Z ,∵α,β都是锐角,∴0°<α+β<180°. 取k =1,得α+β=80°.① ∵α-β=670°+k ·360°,k ∈Z .∵α,β都是锐角,∴{ 0°<α<90°-90°<-β<0°, ∴-90°<α-β<90°.取k =-2,得α-β=-50°.② 由①②,得α=15°,β=65°.7.如图,分别写出适合下列条件的角的集合:(1)终边落在射线OB上;(2)终边落在直线OA上;(3)终边落在阴影区域内(含边界).[解](1)终边落在射线OB上的角的集合为S1={α|α=60°+k·360°,k∈Z}.(2)终边落在直线OA上的角的集合为S2={α|α=30°+k·180°,k∈Z}.(3)终边落在阴影区域内(含边界)的角的集合为S3={α|30°+k·180°≤α≤60°+k·180°,k∈Z}.。
